Thread: Question about contrib

Hello,

I have a question about contrib directory. I know the projects there is 
not official supported by PostgreSQL development team and I wanna ask, 
what will be happened if the leader of project pg_crypto for example (I 
repeat for example) leave the project for example in pgsql 13 and 
project is not added in next major release i.e. 14. What ppl need to do 
if they use this functionality that is not part for one reason or 
another from the main project in pgsql version 14 ?
Or the module has some problems and is not ready until the release of 
the new main version for an example.

I ask because if a module enters the functionality of the project, then 
if this happens it is very difficult to change the whole project so as 
not to use this functionality and you want or do not have to get rid of 
any database updates until a new version of the model appears or the 
whole application is not changed to not use it and this is important and 
will not to be cheep.

Is there any guarantee that a module will continue to work and be 
maintained from another team or PG even if its author terminates support 
and maintains ?

Regards,
HS

Aha my mistake, sorry. Why is not in main tree then ?

Ah thank you,

that was my question and it's seems is true. Did I safety can choice a
module without to worry that one will not work.

Thanks for the answer.

Actually I think the high-level answer is that the contrib modules
exist to verify that Postgres is extensible, and to provide sample
code for other people wanting to make extensions.  It's great that
they have actual use cases, but we'd keep them even if they didn't.

While they're all nominally supported, some are old, crufty, and
deprecated to various extents.  xml2, in particular, might go away
someday.
