PG version?
Maybe worth to try NOT EXISTS instead of NOT IN

Subject: [ADMIN] Too slow
How can I improve speed on my queries. For example this query takes one
day executing itself and it has not finalized !!!
"create table tmp_partes as select * from partes where identificacion
not in (select cedula from sujetos)"
partes have 1888000 rows, an index on identificacion
sujetos have 5500000 rows, an index on cedula

TIP 4: Don't 'kill -9' the postmaster
