Hi,
I'm running into what seems to be the same problem, only we're using MySQL. Here are some logs and a ps auxww from both deletion and creation of servers in batches of 50.
We have two Foreman hosts, I've tried running both against their load balanced address and individually and it doesn't seem to make a difference. Neither one has much load to speak of.
Foreman 1.5.1, Debian 7.5, ruby 1.9.3 running behind Passenger 3.

Oh and the MySQL database in one of the ps outputs is not the one the foreman servers are using, I don't think it's used at all, I'm just not sure enough to just remove it yet.

Hello,

we are facing the same issue when deploying new hosts.
Unfortunately I don't have a reproducer yet and it happens only occasionaly :-/

Foreman API returns following:

 "error": {"message":"PGError: ERROR:  deadlock detected\nDETAIL:  Process 19775 waits for ShareLock on transaction 65552980; blocked by process 23414.\nProcess 23414 waits for ExclusiveLock on tuple (0,25) of relation 16503 of database 16414; blocked by process 19775.\nHINT:  See server log for query details.\n: UPDATE \"architectures\" SET \"hosts_count\" = COALESCE(\"hosts_count\", 0) + 1 WHERE \"architectures\".\"id\" = 1"}

This can be found in postgres logs:
