    they are automatically returned as arrays when fetching. [GSM]
  - Add support for asynchronous queries. [GSM]
  - Allow raw transaction statements through - in other words, 
    do not croak if $dbh->prepare("COMMIT") is attempted. Not 
    only was this a little too controlling, there is a growing 
    host of other commands such as "COMMIT PREPARED" that we

  - Use adbin, not adsrc, when figuring out the sequence name for the 
    last_insert_id() method. This allows the function to work properly 
    if the sequence name is changed. Note that {pg_cache=>0} should be 
    passed to the function if you expect this might happen.
    (CPAN bug #30924) [GSM]
  - Use unsigned chars when parsing passed-in queries, preventing UTF-8 
    strings from ruining the prepare. UTF-16 may still cause problems.

    (CPAN bug #20282) [GSM]
  - Change $dbh->{User} to $dbh->{Username} [GSM]

  - Notice messages generated by the database now use the perl 
    warning mechanism instead of going to stderr.
    [Dominic Mitchell <dom@semantico.com>]
  - $dbh->prepare() rewrites the SQL statement into an internal form,
    striping out comments and whitespace, and if PostgreSQL > 7.3 takes the 
    stripped statement and passes that to Postgres' PREPARE statement, 
    then rewrites the statement as 'EXECUTE "DBD::PG::cached_query n"
    ($1, $2, ... $n, $n+1)' for DBD::Pg's execute.
    -- Currently disabled until PREPARE works a little better
  - Allows the use of :n and :foo bind params. So: 
    (SELECT * FROM foo WHERE 1 = :this and 2 = :that) will now work.
  - Complains on execute when unbound bind params are submitted
    (instead of defaulting to NULL)
  - Switched over to use driver.xst.
  - pg_error() removes \n's rather than truncating the message on the first \n.
  - Fixed statement scan problem where the preparse of
    "SELECT foo[3:33] from bar" was scanning :33 as a placeholder
  - Moved the quoting of bind values out of execute() and into
    bind -- as there is no need to requote the value every time execute 
    is called.
  - :veryverylongplaceholdername == Long walk, short pier -- fixed.
  - quote() is now in C and uses same code as bind_param.
  - Quoting and dequoting now use libpq quoting functions where available
    (I still need to take the libpq functions swiped out of quote.c and move 
    it into libpqswip.c with license info &c., and switch ifndefs to ifdefs)
  - bind_param() will convert from 1,0 to TRUE/FALSE when pg_type
    is PGBOOLOID.
  - Fixed many heap buffer overruns.
  - Added support for the get_info() method [GSM]
  - Added tests for POD validation [Mark Stosberg]
  - Several improvements to column_info, including:
    - Fixed column_info so NULLABLE field shows correctly. [kevin@sysexperts.com]
    - REMARKS field works now [Mark Stosberbg]
    - COLUMN_DEF fixed
    - COLUMN_SIZE fixed
    - pg_constraint column added to display column constraints

    rather than files. Contributed by Garth Webb.
  - Added LISTEN/NOTIFY functionality. Contributed by Alex Pilosov.
  - Added constants for common PostgreSQL data types, plus simple tests to
    make sure that they work. These are exportable via 
    "use DBD::Pg qw(:pg_types);". [David Wheeler]
  - Deprecated the undocumented (and invalid) use of SQL_BINARY in
    bind_param() and documented the correct approach: "bind_param($num,
    $val { pg_type => PG_BYTEA });". Use of SQL_BINARY in bind_param() will
    now issue a warning if $h->{Warn} is true. [David Wheeler]
  - Removed invalid (and broken) support for SQL_BINARY in quote().
    [David Wheeler]
  - Added App::Info::RDBMS::PostgreSQL to the distribution (but it won't
    be installed) to help Makefile.PL find the PostgreSQL include and
    library files. [David Wheeler]
  - Fixed compile-time warnings. [David Wheeler and Jason E. Stewart]
