Both approaches have to do a catalog scan (even if you've established
an exception block the server still internally has to do a catalog
scan in order to raise an appropriate error). The exception block has
the additional overhead of a subtransaction.
OK this makes sense. Thanks :-) I will go for the CREATE TABLE approach.
