Hi,

I doubt that this will improve your pg_restore performance, but if you
have 1600 tables in the database then you very likely want to increase
the above two settings.

In general max_fsm_relations should be more than the total number of
tables across all databases in a given installation. The best way to
set these is to do a "VACUUM VERBOSE", which will print the appropriate
minimum numbers at the end of the run, along with the current setting.

Cheers,
Andrew.
