RPostgres 1.4.6

Breaking changes

• Breaking change: dbListObjects() only allows Id() objects as prefix argument (@dpprdan, #390).

Features

• dbQuoteLiteral() correctly quotes 64-bit integers from the bit64 package (of class "integer64") (@karawoo, #435, #436).

• Breaking change: dbListObjects() only allows Id() objects as prefix argument (@dpprdan, #390).

Libraries

• Windows: update to libpq-15.3 (#442).

• Upgrade boost to 1.81.0-1 to fix sprintf warnings (#417).

Documentation

• Suppress warning in gcc-12 (#443).

• Tweak driver docs (@dpprdan, #433).

• Relicense as MIT.

Testing

• Close result set.

Internal

• One-click setup for https://gitpod.io (@Antonov548, #407).

• Use testthat edition 3 (#408).

RPostgres 1.4.4

Bug fixes

• Allow connection if the pg_type table is missing (#394, #395, @pedrobtz).
• Fix dbExecute(immediate = TRUE) after dbAppendTable() (#382, #384).

Internal

• Expand tests for dbConnect(check_interrupts = TRUE) (#385, @zozlak).
• Ignore extended timestamp tests on i386 (#387).

RPostgres 1.4.3

Features

• New postgresIsTransacting() (#351, @jakob-r).
• Temporary tables are now discovered correctly for Redshift() connections, all DBItest tests pass (#358, @galachad).

Internal

• Make method definition more similar to S3. All setMethod() calls refer to top-level functions (#380).

RPostgres 1.4.2

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).
• With dbConnect(check_interrupts = TRUE), interrupting a query now gives a dedicated error message. Very short-running queries no longer take one second to complete (#344).

Bug fixes

• dbQuoteLiteral() correctly quotes length-0 values (#355) and generates typed NULL expressions for NA values (#357).
• The SET DATESTYLE query sent after connecting uses quotes for compatibility with CockroachDB (#360).

Internal

• dbConnect() executes initial queries with immediate = TRUE (#346).
• Check Postgres starting from version 10 on GitHub Actions (#368).
• Fix build on Ubuntu 16.04 (#352).
• Mention libssl-dev in configure script (#350).

RPostgres 1.4.1

Bug fixes

• Avoid crash by dereferencing 0-size vector (#343).

RPostgres 1.4.0

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).
• dbAppendTable() gains copy argument. If set to TRUE, data is imported via COPY name FROM STDIN (#241, @hugheylab).
• 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).
• dbWriteTable() and dbAppendTable() default to copy = NULL, this translates to TRUE for Postgres() and FALSE for Redshift() connections (#329).

Documentation

• Order help topics on pkgdown site.
• Use @examplesIf in method documentation.
• Document when field.types is used in dbWriteTable() (#206).
• Document setting the tablespace before writing a table (#246).
• Tweak error message for named params argument to dbBind() (#266).

RPostgres 1.3.3

• Fix dbConnect(check_interrupts = TRUE) on Windows (#244, @zozlak).
• Windows: update to libpq 13.2.0 and add UCRT support (#309, @jeroen).
