RPostgres 1.4.2 (2021-12-05)

Features

• dbWriteTable() uses savepoints for its transactions, even if an external transaction is open. This does not affect Redshift, because savepoints are not supproted there (#342).

RPostgres 1.4.0 (2021-09-25)

Features

• Redshift() connections now adhere to almost all of the DBI specification when connecting to a Redshift cluster. BLOBs are not supported on Redshift, and there are limitations with enumerating temporary and persistent tables (#215, #326).
• dbBegin(), dbCommit() and dbRollback() gain name argument to support savepoints. An unnamed transaction must be started beforehand (#13).
• dbWriteTable() uses a transaction (#307).
• dbSendQuery() gains immediate argument. Multiple queries (separated by semicolons) can be passed in this mode, query parameters are not supported (#272).
• dbConnect(check_interrupts = TRUE) now aborts a running query faster and more reliably when the user signals an interrupt, e.g. by pressing Ctrl+C (#336).

• Postgres NOTICE messages are now forwarded as proper R messages and can be captured and suppressed (#208).

Bug fixes

• dbQuoteLiteral() converts timestamp values to input time zone, used when writing tables to Redshift (#325).

Internal

• Skip timestamp tests on i386 (#318).
• dbSendQuery() and dbQuoteLiteral() use single dispatch (#320).

• Remove BH dependency by inlining the header files (#300).
• Use Autobrew if libpq is older than version 12 (#294, @jeroen).
• dbConnect() now issues SET datestyle to iso, mdy to avoid translation errors for datetime values with databases configured differently (#287, @baderstine).

RPostgres 1.3.1 (2021-01-19)

Bug fixes

• Inf, -Inf and NaN values are returned correctly on Windows (#267).
• Fix behavior with invalid time zone (#284, @ateucher).

Internal

• dbConnect() defaults to timezone_out = NULL, this means to use timezone.
• FORCE_AUTOBREW environment variable enforces use of autobrew in configure (#283, @jeroen).
• Fix configure on macOS, small tweaks (#282, #283, @jeroen).
• Fix configure script, remove $() not reliably detected by checkbashisms.
• configure uses a shell script and no longer forwards to src/configure.bash (#265).

RPostgres 1.3.0 (2021-01-05)

• dbConnect() gains timezone_out argument, the default NULL means to use timezone (#222).
• dbQuoteLiteral() now quotes difftime values as interval (#270).
• New postgresWaitForNotify() adds LISTEN/NOTIFY support (#237, @lentinj).

Bug fixes

• Inf, -Inf and NaN values are returned correctly on Windows (#267).
• DATETIME values (=without time zone) and DATETIMETZ values (=with time zone) are returned correctly (#190, #205, #229), also if they start before 1970 (#221).

Internal

• configure uses a shell script and no longer forwards to src/configure.bash (#265).
• Switch to GitHub Actions (#268, thanks @ankane).
• Now imports the lubridate package.

RPostgres 1.2.1 (2020-09-28)

• Gains new Redshift driver for connecting to Redshift databases. Redshift databases behave almost identically to Postgres so this driver allows downstream packages to distinguish between the two (#258).
• Datetime values are now passed to the database using an unambiguous time zone format (#255, @imlijunda).
• Document Postgres() together with dbConnect() (#242).
• Windows: update libpq to 12.2.0.

RPostgres 1.2.0 (2019-12-18)

Communication with the database

• Breaking: Translate floating-point values to DOUBLE PRECISION by default (#194).

• Avoid adding extra spaces for numerics (#216).
• Column names and error messages are UTF-8 encoded (#172).

New features

• Add timezone argument to dbConnect() (#187, @trafficonese).
• Implement dbGetInfo() for the driver and the connection object.
• dbConnect() gains check_interrupts argument that allows interrupting execution safely while waiting for query results to be ready (#193, @zozlak).
• dbUnquoteIdentifier() also handles unquoted identifiers of the form table or schema.table, for compatibility with dbplyr. In addition, a catalog component is supported for quoting and unquoting with Id().
• dbQuoteLiteral() available for "character" (#209).
• Windows: update libpq to 11.1.0.
• Fulfill CII badge requirements (#227, @TSchiefer).

Bug fixes

• Hide unused symbols in shared library (#230, @troels).
• Fix partial argument matching in dbAppendTable() (r-dbi/DBI#249).

• Add tests for dbUnquoteIdentifier() (#220, @baileych).
• Improved tests for numerical precision (#203, @harvey131).
• Fix test: change from REAL to DOUBLE PRECISION (#204, @harvey131).
• Implement dbAppendTable() for own connection class, don’t hijack base class implementation (r-dbi/RMariaDB#119).
• Avoid including the call in errors.
• Align DbResult and other classes with RSQLite and RMariaDB.

RPostgres 1.1.3 (2019-12-07)

• Replace std::mem_fn() by boost::mem_fn() which works for older compilers.

RPostgres 1.1.2 (2019-12-03)

• Replace std::mem_fun_ref() by std::mem_fn().

RPostgres 1.1.1 (2018-05-05)

• Add support for bigint argument to dbConnect(), supported values are "integer64", "integer", "numeric" and "character". Large integers are returned as values of that type (r-dbi/DBItest#133).
• Data frames resulting from a query always have unique non-empty column names (r-dbi/DBItest#137).
• New arguments temporary and fail_if_missing (default: TRUE) to dbRemoveTable() (r-dbi/DBI#141, r-dbi/DBI#197).
• Using dbCreateTable() and dbAppendTable() internally (r-dbi/DBI#74).
• The field.types argument to dbWriteTable() now must be named.
• Using current_schemas(true) also in dbListObjects() and dbListTables(), for consistency with dbListFields(). Objects from the pg_catalog schema are still excluded.
• dbListFields() doesn’t list fields from tables found in the pg_catalog schema.
• The dbListFields() method now works correctly if the name argument is a quoted identifier or of class Id, and throws an error if the table is not found (r-dbi/DBI#75).
• Implement format() method for SqliteConnection (r-dbi/DBI#163).
• Reexporting Id(), DBI::dbIsReadOnly() and DBI::dbCanConnect().

RPostgres 1.1.0 (2018-04-04)

• Breaking change: dbGetException() is no longer reexported from DBI.
• Make “typname” information available after dbFetch() and dbGetQuery(). Values of unknown type are returned as character vector of class "pq_xxx", where "xxx" is the “typname” returned from PostgreSQL. In particular, JSON and JSONB values now have class "pq_json" and "pq_jsonb", respectively. The return value of dbColumnInfo() gains new columns ".oid" (integer), ". known" (logical) and ".typname" (character) (#114, @etiennebr).
• Values of class "integer64" are now supported for dbWriteTable() and dbBind() (#178).
• Schema support, as specified by DBI: dbListObjects(), dbUnquoteIdentifier() and Id().
• Names in the x argument to dbQuoteIdentifier() are preserved in the output (r-dbi/DBI#173).
• All generics defined in DBI (e.g., dbGetQuery()) are now exported, even if the package doesn’t provide a custom implementation (#168).
• Replace non-portable timegm() with private implementation.
• Correct reference to RPostgreSQL package (#165, @ClaytonJY).

RPostgres 1.0-4 (2017-12-20)

• Fix installation on macOS.
• Check libpq version in configure script (need at least 9.0).
• Fix UBSAN warning: reference binding to null pointer (#156).
• Fix rchk warning: PROTECT internal temporary SEXP objects (#157).
• Fix severe memory leak when fetching results (#154).

RPostgres 1.0-3 (2017-12-01)

Initial release, compliant to the DBI specification.

• Test almost all test cases of the DBI specification.
• Fully support parametrized queries.
• Spec-compliant transactions.
• 64-bit integers are now supported through the bit64 package. This also means that numeric literals (as in SELECT 1) are returned as 64-bit integers. The bigint argument to dbConnect() allows overriding the data type on a per-connection basis.
• Correct handling of DATETIME and TIME columns.
• New default row.names = FALSE.
