I need to write a query that will list table name and the number of columns in each table.  

example of results:

table_name    +  # of COLs
table_one     |   20
table_two     |   350


RE: Query

What version of PSQL are you using?  
This one works with PSQL v9.5:
select xf$name, count(xe$name) from x$field, x$file where xe$file = xf$id group by xf$name

RE: Query

now how do I add the number of bytes in a record and the number of rows in the table to the query

RE: Query

That data is not directly available.  The bytes in the record could be counted by using the sum of the XE$SIZE field for each of the tables.  THe record count is not going to be available without issuing a "SELECT COUNT(*) FROM table" query.
