The module is working fine on HEAD without any patch if it cares about
starting a transaction itself into _PG_init(), even when _PG_init() is
called at function call time rather than at local_preload_libraries
time.
My reserve was that I thought the transaction arround _PG_init() was
existing in a 'normal' call, so the explicit creation of it in the
module would fail:
StartTransactionCommand();
...
CommitTransactionCommand();
Now my only problem is related to making the module 8.3 compliant:
pre_prepare.c:19:27: error: utils/snapmgr.h: No such file or directory
pre_prepare.c: In function ‘_PG_init’:
pre_prepare.c:188: warning: implicit declaration of function
‘PushActiveSnapshot’
pre_prepare.c:207: warning: implicit declaration of function ‘PopActiveSnapshot’
I guess I can document that having pre_prepare in
local_preload_libraries with preprepare.at_init = on is only support
from 8.4 onward...
