Обсуждение: Persistent user-defined functions

Hi all,

I am using Ubuntu 7.10 with PostgreSQL 8.2.  I have just finished creating two C functions and have successfully loaded
themusing "CREATE OR REPLACE FUNCTION" ... This was an extremely smooth process, and I have a lot of respect for the
devteam for creating such a robust system. 

Anyway - I would like these new functions to be permanently available to a database, or to all databases.  These
functionswill ultimately be called from PHP, where there is no guarantee of server state in between requests (maybe a
rebootoccurs and my functions are lost, etc...).  On the other hand, it is inefficient to "CREATE OR REPLACE" all the
time. Can anybody suggest a lightweight method to keep these functions permanently available, or point me towards a
resourcethat might assist? 

Best regards,

Dave.

Once you have created a function in a database, it stays until you drop
it. No crash will lose it for example. You will have to do the creation
once for each database and if you create them in template1 they will
automatically appear whenever you create a new database.

Have a nice day,
