Backups of this db are created with:
pg_dump --file=fsm.dmp -Fc --blobs --oids --dbname=lfm --host=localhost
--port=nnnn --username=superuser
From your original post:
"Running Postgres 15.3 ..."
--oids have not been supported with pg_dump since v11
When I try it:
pg_dump -V
pg_dump (PostgreSQL) 15.7 (Ubuntu 15.7-1.pgdg22.04+1)
pg_dump -d test -U postgres --oids -f test.sql
/usr/lib/postgresql/15/bin/pg_dump: unrecognized option '--oids'
So what version of pg_dump are you using?
Or you not working on a v15 instance of Postgres?
FYI, --blobs is only needed when dumping a specific table or schema,
otherwise it happens by default.
Restore is run with:
dropdb --port=nnnn --maintenance-db=postgres --username=superuser --if-exists
lfm
pg_restore -Fc --create --dbname=postgres --port=nnnn --username=superuser
fsm.dmp

2) From earlier post: '... only analyzes tables in the new db at the point of
reload, then shuts off again.' Provide that sequence of events from the
Postgres log.
Log file extract is attached, with object names obfuscated.
Still working my way through that.
From yesterday, current stats for table a.accp, from pg_STAT_all_tables:
"811486381""airscape""accp"16458538988177871456553503047055581967135016364880294000"2024-05-14
14:51:37.158892+00""2024-05-09 08:27:45.328468+00""2024-05-14 13:15:31.999198+00"01815170101653
I can't parse this out well enough to really say anything. Though the
timestamps seem to indicate recent activity.
Using psql do
\x
select * from pg_stat_all_tables where relname = 'a.accp';
to get an extended output that is easier to read.
This table has a low row count, but high content turnover.
It usually gets auto-analyzed every minute.
For today, this hasn't been auto analysed since the update at 3am.
4) The autovacuum settings you have in effect:
vacuum_cost_limit = 2000
log_autovacuum_min_duration = 0
autovacuum_max_workers = 10
all other vacuum settings are defaults.
