Try NULL rather than ''. '' is not a null in postgres.

Thanks, I feel a little sheepish at not trying it with quotes around the
query, but the manuals don't mention that you have to enclose the query in
quotes when you use the -c option.

I was wondering if anyone could help me out with the syntax of
running queries from a unix script.
psql -c select 'I am a dummy' -d dbname - never seems to
work. I've tried variations on the command line, but to no
success.
Does the -c option work?
Cheers,

I imagine it should if you create a unique index on the field.

I have not seen much information about this anywhere on the
web.
If anyone has seen, or written a function similar, could you
please let me know where?
Thanks.
