RPostgres 1.2.0 2019-12-18

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).


  • 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 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) 2018-05-06

  • 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) 2018-04-06

  • 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) 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) 2017-12-06

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.
