well, the tracing is turned off, but I also found two things:
1) the DB server has a bit lower CPU load when using ODBC driver (30% vs
35% with jdbc) and the machine running the program has a bit higher CPU
load with (6-7% vs 5% with jdbc)
2) pg_stat_activity shows proper prepared statement when using jdbc,
something like:
insert into my_table (col1, col2) values ($1, $2)
but when I use ODBC driver the statement looks like a non-prepared one:
insert into my_table (col1, col2) values (2024443, E'MYTEXT1')

I wander if pgsql odbc driver does not support prepared statement (or I
need to turn some flag on)
