Bad plan

Hello all,

So I have a view, for which I can select all rows in about 3s (returns ~80k
rows), but if I add a where clause on a column, it takes +300s to return
the ~8k lines.

From the plan, I see that it expects to return only 1 row and so choose to
perform some nested loops. Of course, I did run "ANALYZE", but with no
success.

I managed to speed things up with "set enable_nestloop = false;", but is
that the only choice I have ? Should I report a bug ?

The view is this :
