Error with DBD::Pg (2 messages)

I am moving some web applications from Oracle to Postgres, and on one system I’m getting the following error:


[Fri Oct 27 13:25:19.725785 2023] [:error] [pid 98181:tid 98230] DBD::Pg initialisation failed: Can't locate object method "driver" via package "DBD::Pg" at /usr/lib64/perl5/vendor_perl/DBI.pm line 829.\n\nPerhaps the capitalisation of DBD 'Pg' isn't right. at /home/allwebfiles/perl/LocalModules/Cal4Defaults.pm line 49.\nCompilation failed in require at /home/allwebfiles/perl/LocalModules/Cal4HTML.pm line 10.\nBEGIN failed--compilation aborted at /home/allwebfiles/perl/LocalModules/Cal4HTML.pm line 10.\nCompilation failed in require at /home/allwebfiles/perl/roomgrid.pl line 8.\nBEGIN failed--compilation aborted at /home/allwebfiles/perl/roomgrid.pl line 8.\n

Thing is this is the second server I'm working on, and the first is pretty much identical

Both are Rocky Linux 9.5 (a replacement for CentOS)

DBD::Pg was installed via cpan Bundle::DBD::Pg

PostgreSQL and DBI both come from the Rocky repositories

The line 49 in the .pm in question is :

my $lda = DBI->connect("dbi:Pg:$dbname", $login, $dbpass, {RaiseError=>0, AutoCommit=> 1, PrintError =>1});

$dbname is ‘db=my_db_name;host=my_postgres_host;port=3542’ and is the same on the working system

All the references Ive found online regarding this error message were because DBD::Pg wasn’t installed which is not the case:


cpan[1]> i Bundle::DBD::Pg

Any ideas?
