Dear PGD,

I would like to know something, becouse I can't find answer in the
Postgres documentation. I use libpq, and when I create an exsisting
table, PQexec function returns a null pointer. But I need an error code,
becouse I want to treat this problem. Can anybody tell me how I can get
this desired error code? 

I need to know, what tables exist in the database (by libpq functions),
but I can't find anything about that in the manual.

Dear Jackson De Huan,
I wrote in my previous letter:

Thank you for your answer. I had tried to execute a vacuum command in
psql, but it didn't help. If I destroy and recreate my database,
everything become perfect. But it isn't too comfortable. (I use my
database not as postgres but as gyurika user. I've created a postgres
user, whose name is gyurika. ).

Thanks for your attention!
