Corrupted server name in DBI or DBD::Pg

paulbort has asked for the wisdom of the Perl Monks concerning the following question:

Fellow Monks,

I have, in the process of upgrading my Request Tracker server from RedHat 8.0 to Fedora Core 2, seriously broken DBI and DBD::Pg.

I have removed the DBI and DBD::Pg RPMs, and installed (from CPAN) fresh copies of both, without error. But when I try to run my simple test program, things go strange:

#!/usr/bin/perl
use DBI;
use DBD::Pg;

my $dbh = DBI->connect( 'dbi:Pg:dbname=template1;host=localhost',
                        'postgres', undef );

die DBI->errstr;

The output is as follows:

DBI connect('dbname=template1;host=localhost','postgres',...) failed: 
+could not connect to server: D礔濃攡_O at /root/test.pl line 8
could not connect to server: D礔濃攡_O at /root/test.pl line 10.

I know I've broken something while flailing about, and I hate asking for help with my own mistakes, but I'm stuck. If I change the DSN, the strange characters change, but seem to always start with a 'D'. I've searched Google and the monastery with no luck.

Relevant details:

Perl 5.8.3 (from Fedora Core 2 RPM, multi-threaded)
DBI 1.43
DBD::Pg 1.32
PostgreSQL 7.4.2 (Also from RPM)
psql works normally.

@INC includes the following, but I have no idea if this is sane or not:

/usr/lib/perl5/5.8.3/i386-linux-thread-multi
/usr/lib/perl5/5.8.3
/usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.2/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.1/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi

/usr/lib/perl5/vendor_perl/5.8.1
/usr/lib/perl5/vendor_perl/5.8.0

Thanks in advance.

Update:Never Mind, I didn't see the forest for the trees. Props to hsinclai for the gentle reminder.

Hey paulbort - is your `pg_hba.conf` set up correctly? What is in your postgres log? It will probably have the clues!	[reply] [d/l] [select]

AAUUGGHH! In one of my earlier flailing attempts, I re-installed PostgreSQL, and didn't re-enable sockets (in both postgresql.conf and pg_hba.conf.) Thank you for ponting out the blindingly obvious. But I still don't get the bizarre mangling of the servername -- Spring: Forces, Coiled Again!	[reply]
