ALTER EXTENSION UPDATE: How to update the 'module_pathname'?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

after installing an extension with functions with C bindings - CREATE OR REPLACE FUNCTION ... AS 'MODULE_PATHNAME' LANGUAGE C ... - I like to change the 'module_pathname' upon its update. After reading the docs and especially the section of 'ALTER EXTENSION' I have the feeling, that this operation is not possible.

First tries lead to the assumption, that the control-file is not re-parsed in order to reflect any changes in the 'module_pathname'. I'm correct with my observation? Is this 'module_pathname' somewhere stored in the internals of some pg_tables? If yes, it should be possible to update this entry and call ALTER EXTENSION UPDATE again.

What I do not want to do is a DELETE/CREATE EXTENSION process.

Any suggestions?

Regards,
Henrik
