make check ERROR: unrecognized configuration parameter "postgis.backend"

[strk]

Running

make check RUNTESTFLAGS='-v --extension --upgrade-path=2.0.5--2.2.0dev'

I get the error:

+ERROR:  unrecognized configuration parameter "postgis.backend"

It sounds like the "postgis.backend" GUC parameter is not installed on upgrade, but only on new install, can it be ?

This could be related:

Preparing db 'postgis_reg' using: CREATE EXTENSION postgis VERSION '2.0.5'
Upgrading PostGIS in 'postgis_reg' using: ALTER EXTENSION postgis UPDATE TO '2.2.0dev'
ERROR:  function postgis_sfcgal_version() does not exist

[strk]

It sounds related to #2754

Should run_test get a new switch to load the sfcgal script/extension ? like —topology is used for topology ?

[strk]

r12766 fixes the support for —extension and sfcgal switch, fixing the "postgis_sfcgal_version" availability during testing.

But still, the 'unrecognized configuration parameter "postgis.backend"' comes out on make check (no matter upgrade switches)

[strk]

NOTE: this is when running against 9.1.13, so could be that at that time the database needs to be instructed to recognize the GUC (likely).

[strk]

Confirmed, it's about 9.1.x needing an explicit configuration to recognize namespaced GUCs. Not sure how to deal with this at "make check" time. Maybe GUC testing should be disabled for 9.1 ? Or only if custo_variable_classes does not contain "postgis" ?

I cannot reproduce anymore. Will file a new one if anything else comes out.
