Re: pqlib large object error

Thanks for all your help. I'm somewhat amateur with C and even less
experienced with PostgreSQL (I'm a recent MySQL convert). Even after
some googling, I have no idea what this BEGIN block is. Is it C or is it
SQL? That probably makes me a n00b. :-| If you could explain I'd
appreciate it :-)

BTW once I get this working I'm going to write a PostgreSQL Large Object
tutorial on my blog, so others don't have to struggle with the code like
I am :-)
