RPostgres 1.2.0

Communication with the database

• Breaking: Translate floating-point values to DOUBLE PRECISION by default (#194).
• Avoid aggressive rounding when passing numeric values to the database (#184).
• Avoid adding extra spaces for numerics (#216).
• Column names and error messages are UTF-8 encoded (#172).
• dbWriteTable(copy = FALSE), sqlData() and dbAppendTable() now work for character columns (#209), which are always converted to UTF-8.

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).
• Fix binding for whole numbers and POSIXt timestamps (#191).

Internal

• sqlData(copy = FALSE) now uses dbQuoteLiteral() (#209).
• 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

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

RPostgres 1.1.2

• 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().
• Now imports DBI 1.0.0.

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-lib/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)

• Only call PQcancel() if the query hasn’t completed, fixes transactions on Amazon RedShift (#159, @mmuurr).
• 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.
