Hmm. RelationBuildRuleLock is concerned with reading the rule
information for a table; specifically, it's evidently trying to
read the rules for v_psl_package_info. I suspect some form of
data corruption in the pg_rewrite row(s) for this table. Do you
see any misbehavior when you do

select * from pg_rewrite where ev_class = 'v_psl_package_info'::regclass

In particular, are any of the columns NULL in these rows?
