Hi, i found this form of output of explain analyze, watching some old
mails in lists.
test4=# explain analyze select * from patients;
LOG: query: explain analyze select * from patients;

QUERY PLAN
-----------------------------------------------------------------
Seq Scan on patients (cost=0.00..4048.60 rows=131960 width=172)
(actual time=0.04..562.97 rows=133886 loops=1)
Total runtime: 602.42 msec
(2 rows)
How can i turn my configuration to achieve this output for explain
analyze (and only the QUERY PLAN, as like tomorrow)?

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
