I’ve wanted this for a long time. I think it would have to create a temporary 
cluster, fire up a server, install the extension(s), run the tests, shut down 
the server and delete the cluster.

Right, then pg_regress could just be the default test framework.

Isn't that the existing EXTRA_INSTALL?


No. The problem is that "make check" doesn't work extensions built
outside the server source tree. You get an error:

"make check" is not supported.
Do "make install", then "make installcheck" instead.


I would love it if make check worked. make installcheck adds extra 
effort to extension develoopment, not to mention leaving your actual 
install in a less than pristine state.

One problem we have with PostGIS is you cannot test an extension
unless you have access to the system extension dir.

The following patch tries to address that by allowing to specify
a per-cluster extension path via an "extensions_path" GUC.

It is more a request-for-comments rather than a ready patch, as
I hadn't considered all use cases like upgrades of already-loaded
extensions and the possibility ot have a list of directories to
seek for extensions.

Anyway, patch is attached.


This would be very useful. I proposed this previously in February, but 
that implementation (almost identical to yours) was rejected.


https://commitfest.postgresql.org/5/170/
http://www.postgresql.org/message-id/54e3c31f.8010...@ohmu.fi

Both of these implementations miss a way to override the path for 
extension .so files.

This was discussed a while ago already, see 
http://www.postgresql.org/message-id/51ae0845.8010...@ocharles.org.uk.


In short, I don't think just setting extensions_path is enough or 
desirable, but I would welcome a patch that makes "make check" work for
