Perl - DBI en .pgpass

JA! Er IS een betere manier.

Wissel eenvoudig tussen test- en liveservers.

• bewaar wachtwoorden in ~/.pgpass (voor psql &pg_dump )
• andere configuratie-informatie in ~/.pg_service.conf (of /etc/pg_service.conf )

bijvoorbeeld:

#!/usr/bin/perl -T
use strict;
use warnings;
use DBI;

my $dbh = DBI->connect
(
    #"dbi:Pg:service=live",
    "dbi:Pg:service=test",
    undef,
    undef,
    {
        AutoCommit => 0,
        RaiseError => 1,
        PrintError => 0
    }
) or die DBI->errstr;

~/.pg_service.conf:

# http://www.postgresql.org/docs/9.2/static/libpq-pgservice.html
# /usr/local/share/postgresql/pg_service.conf.sample
# http://search.cpan.org/dist/DBD-Pg/Pg.pm
#

[test]
dbname=hotapp_test
user=hotusr_test
# localhost, no TCP nonsense needed:
host=/tmp

[live]
dbname=hotapp_live
user=hotusr_live
host=pgsql-server.example.org

~/.pgpass:

# http://www.postgresql.org/docs/9.2/static/libpq-pgpass.html
# hostname:port:database:username:password
