Thread: pgsql: Change this script to Perl 5 style.

Log Message:
-----------
Change this script to Perl 5 style.  Add support for multiple refnames.
Sort the output by command name.  This previously only worked by source
file name, which doesn't always match the command name exactly.  And it
certainly won't work for multiple refnames.
