Обсуждение: DBD::Pg or DBI breakage?

I've been having trouble getting the proper value of $handle->errstr
or $DBI::errstr. For some reason, it's always giving the scalar 7 back
rather than an informative error message. Here's an script and output:

--- foo.pl ---
#!/usr/bin/perl

use DBI;
my $dbh = DBI->connect("dbi:Pg:dbname=template1", "xach", undef);

my $sql = "bogus sql goes here";
my $sth = $dbh->prepare($sql);
$sth->execute() or die $sth->errstr;

my ($result) = $sth->fetchrow_array();

$sth->finish;

print $result, "\n";
$dbh->disconnect();
--- end ---

When run, it prints out this:
  $ perl foo.pl   DBD::Pg::st execute failed:  at foo.pl line 8.  7 at foo.pl line 8.  Database handle destroyed
withoutexplicit disconnect.
 

Now, I'm not surprised at the "database handle destroyed..." part, but
I can't figure out why i'm getting "7 at foo.pl" and a blank message
in the execute failed string. Any ideas?

Try disabling automatic error checking...after the call to DBI->connect, do
this:

$dbh->{PrintError} = 0;
