Hi all have a dought about explain of postgres
Let's see:
Who have more cost for database:
Index Scan using xix3_movimento_roteiro_empresa on movimento_roteiro_empresa movimentor0_ (cost=0.00..73386.80 rows=5126 width=451)
Index Cond: (mrem_ammovimento = 200906)
Filter: ((ftgr_id = 26) AND ((mrem_icatualizarleitura IS NULL) OR (mrem_icatualizarleitura = 2)) AND (mrem_tmleitura IS NOT NULL))
or
Aggregate (cost=26573.78..26573.79 rows=1 width=4)
-> Index Scan using xix4_movimento_roteiro_empresa on movimento_roteiro_empresa movimentor0_ (cost=0.00..26560.41 rows=5347 width=4)
Index Cond: ((ftgr_id = 26) AND (mrem_ammovimento = 200906))
