how to run the equivalent of 'make install check-world' with meson

Hello,

I'm tring to run the equivalent of "make installcheck-world" with meson.

According to https://wiki.postgresql.org/wiki/Meson?utm_source=chatgpt.com:

I have tried:

meson test -C build -q --print-errorlogs --setup running

But these tests fails because it looks like that test extensions are not
installed:

#  step s1exec: LOAD 'delay_execution';
#            SET delay_execution.post_planning_lock_id = 12345;
# -          SELECT * FROM foo WHERE a <> 1 AND a <> (SELECT 3);
<waiting ...>
# +          SELECT * FROM foo WHERE a <> 1 AND a <> (SELECT 3);
# +ERROR:  could not access file "delay_execution": No such file or
directory

 -- Tests for relation options
#  CREATE EXTENSION dummy_index_am;
# +ERROR:  extension "dummy_index_am" is not available
# +HINT:  The extension must first be installed on the system where
PostgreSQL is running.

CREATE EXTENSION dummy_seclabel;
# +ERROR:  extension "dummy_seclabel" is not available
# +HINT:  The extension must first be installed on the system where
PostgreSQL is running.

Here is the full script that I'm using :

export PGDATA=/var/lib/pgsql/data
export TARGET=/var/lib/pgsql/local
set -x
#
rm -rf build
make distclean
meson setup build --prefix=$TARGET --buildtype=debug -Dcassert=true
-Duuid=e2fs -Dssl=openssl -Dtap_tests=enabled -Dliburing=enabled
cd build
ninja
#
rm -rf $TARGET
mkdir $TARGET
#
ninja install
#
export PATH=$TARGET/bin:$PATH
#
pg_ctl stop
rm -rf $PGDATA
initdb
#
echo "logging_collector = on" > $PGDATA/mypg.conf
echo "log_directory = 'log'" >> $PGDATA/mypg.conf
echo "log_filename = 'pg.log'" >> $PGDATA/mypg.conf
echo "include = 'mypg.conf'" >> $PGDATA/postgresql.conf
#
pg_ctl -D $PGDATA -l logfile start
#
cd ..
meson test -C build -q --print-errorlogs --setup running
