Here are my notes from the testing pg_tde:
Install sisis-pap v73 and create a PostgreSQL 16.2 cluster the
usual way, load a database dump into it (all done on
srap21dxr1.dev.oclc.org)
I followed exactly https://github.com/Percona-Lab/pg_tde?tab=readme-ov-file
psql -Usisis sisis
psql (16.2)
Type "help" for help.
sisis=# ALTER SYSTEM SET shared_preload_libraries = 'pg_tde';
(PostgreSQL restart)
...
The notes have been done by cut&paste into a text file. The psql
was fired up against the 16.2 server as it says above. And we also
have never two servers up at the same time.
Maybe later I did it accidently against the 15.1 server from the psql
history. I just tested it in the 15.1 server: it does not give any
error:
psql -Usisis sisis
psql (15.1)
Type "help" for help.
sisis=# ALTER SYSTEM SET shared_preload_libraries = 'pg_tde';
ALTER SYSTEM
sisis=#
and the file gets modified :-(
Why it does not give an error because the shared lib isn't there?
