I have been reading in the dox that pgsql does not support cursors
from inside any of the interfaces, well the ones I care about anyways
which are PL and SPI...
I'm using SPI to spawn an external process to run... (image
manipulator), and I want to be able to control concurrent executions
of the process. I figure setting up a semaphore using an exclusive
record lock is my best bet...
Can anyone tell me if there is a way of doing this, maintaining a
lock
while its away processing while using either PL/pgsql or SPI...
I mention the cursors because it is clear that they cannot be done
without a patch, but it is unclear whether locks and
transactions/commits/rollbacks are supported here.
Thankyou..
scott
