That's not particularly credible ... were you testing this in a

on the inside of a nestloop.

Hi,
could you please post the complete code that you used to create the function.
It sounds suspicously, that pg thinks 'testtable' is a coloum.
Have you set proper quotes in your function-code?
Maybe i got some mistakes regarding the usage of quote_literal in my sample
code.
Till later

Hi,
thank you for your detailled answer!
Today I had the possibility to test it in the office. The procedure

But when I call it SELECT create_geom_table('testtable') Then an error
