Just FYI, I did a quick search-and-replace on your dump to replace
varchar(1) by "char", which makes the column fixed-width without any
change in the visible data. This made hardly any difference in the
join speed though :-(. So that is looking like a dead end.
I'll try to change the data type to bool but the problem I stand in
front of is that the code expects that SELECTs return 'Y' or 'N' but
what I have found out till now is that PostgreSQL returns 't' or 'f' for
bool data. I think about some solution but they use CPU :-(
John's idea about re-joining to the main table to pick up the bulk of
its fields only after joining to the sub-tables might work.
I'll try that. It seems it could work.
