Hello,
If you are a newbie :) I would suggest taking a slightly simpler approach by using prepared queries. Prepared queries will give you the stored plan, albeit per connection.
E.g:
PREPARE FOO AS SELECT ....
EXECUTE FOO;
Sincerely,

Hi!
I'm new to PostgreSQL (and C) and what I'm trying to do is to store a query plan on disc (in a binary file). My approach is to use SPI functions to get the query plan and then transform it into a 'storable' format (Replacing the pointers with actual values).
Is there any other way to do this? Is my approach OK? The sure thing is that it is a messy task!
I posted this message to the 'general' and 'novice' lists but the only answer I got was from the latter:
" I'd look at extending the outfuncs/readfuncs code to deal with
all the node types used in plan trees, and then store text
strings instead of binary.

which seems a little confusing to me since as I said I'm a newbie.
Thanks in advance,
ntinoas
