Hi all, this could be trivial, but I would like an explaination: if I turn off sequential scans on a table without indexes, the same access plan is increased by a 10000000000 factor. I suspect this is a warning for me to remind that something is misconfigured, or is there anothe reason? testdb=# create table tseq( pk serial ); CREATE TABLE testdb=# explain select * from tseq; QUERY PLAN -------------------------------------------------------- Seq Scan on tseq (cost=0.00..35.50 rows=2550 width=4) (1 row) testdb=# set enable_seqscan to off; SET testdb=# explain select * from tseq; QUERY PLAN --------------------------------------------------------------------------- Seq Scan on tseq (cost=10000000000.00..10000000035.50 rows=2550 width=4) (1 row) testdb=# show server_version; server_version ---------------- 12.5 Thanks, Luca
