it is a regular sql command :
use pgadmin or psql
vacuum full analyze;
i'll do a full analysis vacuum to my DB ok.
To execute by pieces, there are many possibilities,
one would be to use pgscript.
The idea is to split your big query into smaller queries.
and , how can i do it, i mean, how can i split my big query, in the case
of only this
"CREATE TABLE SPLITED AS
SELECT ST_Split(b.the_geom,z.the_geom) AS the_geom
FROM public.mapa_base_141213 b, public.all_lines_merged z;"
how can i do it

most likely you havn't !
I don't know your os so answering is difficult.
y have XP sp2, and 1Gb of ram, dual core 1.6ghz
If you have the size of fb free on list,
you can try a
VACUUM FULL ANALYZE
then try again =)
Other wise, you may have to do you computing piece by piece.
how can i do this
