[GENERAL] HELP NEEDED: Recreating DROP columns

Hello!

I have dropped some columns and have quite some problems now with RECTYPE
variables types.

My question: Can I RECREATE dropped columns?

I checked the pg_attribute table and there I can change values of attname,
attstattarget and attisdropped
for my column. Will this work? Is there any side affect?

Thanks,
Damjan
