thx a lot for your answer :)
2) default_statistics_target is set to (default) 100 and there no special
statistics per-column
3) i will do that very soon
4) in absolute units i can see the same query having similar stats to these:
parse -> 600 ms
bind -> 300 ms
execute -> 50 ms
the query mentioned above is a simple select from one table using using two
where conditions. and this table has 1 additional index (except the primary
key) on the columns that are part of the where clause
