Having done a series of
CREATE TEMP TABLE snap_user_idx AS SELECT * FROM pg_stat_user_indexes;
SELECT t1.indexrelname,t1.idx_scan-t0.idx_scan as idx_scan,
t1.idx_tup_read-t0.idx_tup_read AS idx_tup_read,
t1.idx_tup_fetch-t0.idx_tup_fetch as idx_tup_fetch
FROM pg_stat_user_indexes t1 JOIN snap_user_idx t0 USING (indexrelid)
ORDER BY 4;

....it occured to me I'm probably reinventing the wheel. There should already
be a utility which could present all those marvels hidden in 'pg_stat%' tables,
present them as nice graphs, highlight most used indexes, etc, etc.

Maybe one of you is already using such a thing and can direct me to it?

For basic graphing needs I've used MRTG:

There's also cricket, cacti, NRG, etc. Any decent network management
system should support custom scripts or plugins to monitor anything
you can measure.
