Re: Re: Unterminated quoted string error. - Mailing list pgsql-jdbc

Hi Barry,

I looked in the postgresql documentation and couldn't find any mention
of a "bytea" type. Well actually, I found ..

$ grep -i bytea *
bki-commands.html:>bytea</TT
catalog-pg-proc.html:>bytea</TT
xfunc-c.html:>bytea</TD
xfunc-c.html:>(bytea *)</TD

but no real info on what it is, or no mention of it in the main types page.
Anyway, I think I'm fine for now, stipping the null chars from my data.

Tom.
