List pgsql-sql
I have a simple perl script to find out what cause "parse error near .."
The idea is just parse input file and copy to DB using psql line by line.
It's stupid but it helps me several times.
file has following structure ( it's what I prepare for import to DB,
but import failed on some reason):

COPY XXX FROM stdin using delimiters '|';
..............
\.
COPY YYY FROM stdin using delimiters '|';
..............
\.
......
etc

#!/usr/local/bin/perl
# simple wrapper for psql, good to see why copy fails
# tt.pl < file.out | grep ERR
# Oleg Bartunov

my $PSQL = '/usr/local/pgsql/bin/psql -q';
my $DB   = 'flats';
my $FOOT = q^\.^;

my $i = 1;
while (<>) { chomp; $COPYLINE = $_; if ( /^COPY .*;$/ ) {              # skip HEADOFBUFFER   $HEAD = $_;
     # #   print "HEAD = $HEAD\n";   next; } next if ( $COPYLINE =~ /^\\\./ );  # skip ENDOFBUFFER next if ( $COPYLINE
=~/^--/ );    # skip comment line
 

#  print "$i:$COPYLINE\n"; open(OUT, "| $PSQL  $DB"); print OUT "$HEAD\n$COPYLINE\n$FOOT"; close(OUT); print "ERROR!!!
$i:$COPYLINE\n"if( $? ); $i++;
 
}

You got the idea :-)
