    Perl PostgreSQL driver DBD::Pg 3.0.0 released

    Greg Sabino Mullane

    By Greg Sabino Mullane
    February 7, 2014

    I am happy to announce that version 3.0.0 of DBD::Pg, the Perl interface to Postgres, was released on February 3, 2014. This represents a major release, mostly due to the way it now handles UTF-8. I will try to blog soon with more details about that and some other major changes in this version.

    The new version is available from CPAN. Please make sure that this is the latest version, as new versions may have come out since this post was written.

    Checksums for 3.0.0:

    The complete list of changes is below. Thank you to everyone who sent in patches, helped debug, wrote bug reports, and helped me get this version out the door!

    Version 3.0.0  Released February 3, 2014 (git commit 9725314f27a8d65fc05bdeda3da8ce9c251f79bd)
      - Major change in UTF-8 handling. If client_encoding is set to UTF-8, 
        always mark returned Perl strings as utf8. See the pg_enable_utf8 docs
        for more information.
        [Greg Sabino Mullane, David E. Wheeler, David Christensen]
      - Bump DBI requirement to 1.614
      - Bump Perl requirement to 5.8.1
      - Add new handle attribute, switch_prepared, to control when we stop 
        using PQexecParams and start using PQexecPrepared. The default is 2: 
        in previous versions, the effective behavior was 1 (i.e. PQexecParams 
        was never used).
        [Greg Sabino Mullane]

      - Adjust lo_import_with_oid check for 8.3
        (CPAN bug #83145)
      - Better handling of libpq errors to return SQLSTATE 08000
        [Stephen Keller]
      - Make sure CREATE TABLE .. AS SELECT returns rows in non do() cases
      - Add support for AutoInactiveDestroy
        [David Dick] (CPAN bug #68893)
      - Fix ORDINAL_POSITION in foreign_key_info
        [Dagfinn Ilmari Mannsåker] (CPAN bug #88794)
      - Fix foreign_key_info with unspecified schema
        [Dagfinn Ilmari Mannsåker] (CPAN bug #88787)
      - Allow foreign_key_info to work when pg_expand_array is off
        [Greg Sabino Mullane and Tim Bunce] (CPAN bug #51780)
      - Remove math.h linking, as we no longer need it

        implicit index creation is now quieter in Postgres.
        [Erik Rijkers]
      - Use correct SQL_BIGINT constant for int8
        [Dagfinn Ilmari Mannsåker]
      - Fix assertion when binding array columns on debug perls >= 5.16
        [Dagfinn Ilmari Mannsåker]
      - Adjust test to use 3 digit exponential values
        [Greg Sabino Mullane] (CPAN bug #59449)
