Problems on inserting with DBD::Pg

Hi,
I'm using perl 5.6, DBD::Pg with Peter's patch to enable full error
messages (Thanks !!) and I'm having a problem doing an insert. Here's the
extracts of code.

here's the prepare of the statement handle.

$sth_insert = $dbh->prepare("INSERT INTO PEOPLE (userid, title, fname,
sname, email, add_house, add_street, add_area, add_town, add_county,
dd_country, add_code, tel1, tel2, fax, sms, preferred_contact,
registered_date, last_logon_date)
VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,SYSDATE,SYSDATE)")
or die "<p> unable to prepare statement /n<p> $DBI::errst<p></body></html>";

then later the execute

$sth_insert->execute($userid,$title,$forename,$surname,$email,$house,$street
,$blankadd,$town,$county,$country,
$pcode,$tel1,$tel2,$fax,$sms,$preferred_contact) or die "<p> unable to
insert statement /n<p> $DBI::errstr<p></body></html>";

The error message reported is

[Tue May 8 20:25:27 2001] newuser.plx: DBD::Pg::st execute failed: ERROR:
parser: parse error at or near "ail" at /......./cgi/newuser.plx line 161.

Now, line 161 is the execute line. The only occurrences of "ail" (without
the quotes) anywhere near that line is in $email.

Anyone any ideas why it's failing there ? (the basic code worked when we
were using DBD::Oracle, all we've changed is the connect and dbh->prepare
code)

Thanks.
