This is perfectly OK. count(*) from table is generally slow. There are some ways to make it faster (depending if you need exact count, or some estimate). > I'd appreciate it if someone could share his/her thoughts on this.

You can keep the count of elements in this table in separate table, and update it with triggers. > Any query I'm running that joins with transactions table takes forever > to complete, but maybe this is normal for a table this size. As for other queries - show them, and their explain analyze. Performance of count(*) is dependent basically only on size of table. In case of other queries - it might be simple to optimize them. Or impossible - without knowing the queries it's impossible to tell. Do you really care about count(*) from 60m+ record table? How often do you count the records? Best regards, depesz
