Hi,
I tried to use `REGRESS_OPTS = --temp-config` in order to test a 3rd
party extension with a custom .conf file similarly to how PostgreSQL
does it for src/test/modules/test_slru. It didn't work and "38.18.
Extension Building Infrastructure" [1] doesn't seem to be much help.
Here is my Makefile:
```
EXTENSION = experiment
MODULES = experiment
DATA = experiment--1.0.sql experiment.conf
REGRESS_OPTS = --temp-config
$(top_srcdir)/../../../share/postgresql/extension/experiment.conf
REGRESS = experiment
PG_CPPFLAGS = -g -O0
SHLIB_LINK =
ifndef PG_CONFIG
PG_CONFIG := pg_config
endif
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
```
And the result I get:
```
$ make clean && make install && make installcheck
...
# note: experiment.conf is copied according to DATA value:
/bin/sh
/Users/eax/pginstall/lib/postgresql/pgxs/src/makefiles/../../config/install-sh
-c -m 644 .//experiment--1.0.sql .//experiment.conf
'/Users/eax/pginstall/share/postgresql/extension/'
# note: --temp-conf path is correct
echo "# +++ regress install-check in +++" &&
/Users/eax/pginstall/lib/postgresql/pgxs/src/makefiles/../../src/test/regress/pg_regress
--inputdir=./ --bindir='/Users/eax/pginstall/bin' --temp-config
/Users/eax/pginstall/lib/postgresql/pgxs/src/makefiles/../../../../../share/postgresql/extension/experiment.conf
--dbname=contrib_regression experiment
# +++ regress install-check in +++
# using postmaster on Unix socket, default port
not ok 1 - experiment 382 ms
# note: shared_preload_libraries had no effect and I got elog() from
the extension:
$ cat /Users/eax/projects/c/postgresql-extensions/007-gucs/regression.diffs
...
+FATAL: Please use shared_preload_libraries
```
This comment in Makefile for test_slru seems to explain why this happens:
```
# Disabled because these tests require "shared_preload_libraries=test_slru",
# which typical installcheck users do not have (e.g. buildfarm clients).
NO_INSTALLCHECK = 1
```
The complete example is available on GitHub [2].
Is it accurate to say that the author of a 3rd party extension that
uses shared_preload_libraries can't be using SQL tests and has to use
TAP tests instead? If not then what did I miss?
