For table foo,
select count(*) from foo;
An up-to-date count of the number of actual rows is not stored some
place in the database. If an estimate is adequate for your purposes,
you might want to look at some of the system tables which track row
counts for query planning strategy. I don't recall offhand which
column of which system table you'd want to look at, unfortunately.
