Hello,
You can use the information_schema.* tables, which are part of the SQL
standard (and thus not proprietary).

Hi,
I have a problem in that I need to drop non-existent tables in a DDL
script. This is in order that the script can re-build a database
schema if the tables already exist. However, in Postgres this is
proving to be a problem because if the table does not exist then the
DDL execution will stop once it gets an error. I know that I can
create a custom function that will check the relevant postGres table
to see if the table already exists, but I don't want to do this as I
would like to keep the DDL as non-proprietary as possible. Anyone any
ideas on a work-around for this problem that does not involve creating
a custom function.
thanks,
Richie.
