Hi all,
I'm not able to reproduce it anymore but I seen this after a
deadlock detection involving a subtransaction:

ERROR:  deadlock detected
DETAIL:  Process 31330 waits for ShareLock on transaction 570; blocked by process 31328.
Process 31328 waits for ShareLock on transaction 572; blocked by process 31330.
regression=# abort;
WARNING:  cannot remove lock from HTAB
ROLLBACK

I don't have any HTAB around!!


Basically this is what I did:

begin;                       begin;
update record 1;             savepoint a;
~                             update record 2;
update record 2;
~                             update record 1;
~                             <dead lock detected>



I hope that looking at the code is possible understand what the problem is
( if exists ).


Regards
Gaetano Mendola
