Something must be different. As requested by others, try posting the
SQL code chunks, more eyeballs make bugs shallower ( it's happened
several times to me, make a typo, go over it for half an hour, grab a
colleague, she immediately points to it )

It shouldn't be, this I why several perople are requesting to see the
relevant code. Experience says lots of this fails are pilot error.

As an aside, with recent postgres versions you can normally use the
returning construct to grab autogenerated id. I.e., instead of "insert
blah-blah-blah, select currval(), whatever else" you can many times do
"insert balh-blah-blah returning auto_gen_column, whatever else". I've
used it a lot, and normally leads to shorter/easier/faster code.
