I've done as you suggested and I've got the correct directories. I
have a second question now. There are forty-four numeric entries in
the directory for the first databases that I looked at. The database
in question has only eight tables. There are eight tables that have
recent dates. Do I need the total of all the files or just the eight
that appear to be the tables that are being updated?
Take the whole directory - there are indexes as well. And large tables
are split up AFAIK.
You may try the following shell script to determine the size of all
databases:
#!/bin/bash

$PSQLBIN $PGOPTS -p $PGPORT -t -F " " -A template1 -c 'select

choose an index scan if your joining column's datatypes do not
match
