Hello

regress tests fails:

plancache ... ok
limit ... ok
plpgsql ... ok
copy2 ... ok
temp ... FAILED
domain ... ok
rangefuncs ... ok
prepare ... ok
without_oid ... ok
conversion ... ok
truncate ... ok
alter_table ... ok
sequence ... ok

I did some small tests and it works well. When I looked to code, I was
surprised by hardcoded max nesting level of autonomous transactions

#define MAX_AUTOX_NESTING_LEVEL 3

why? Is not it too restrictive?

I am missing a regress tests.

Regards

Pavel
