Expecting to have "100".

  What is the minimal table definition (i.e., a one or few column
table) that would produce this expected value?

CREATE TABLE IF NOT EXISTS leagues(id integer primary key, name
varchar(100), drafttype integer, scoringtype integer, roundvalues
integer, leaguetype char(5), salary integer, benchplayers integer);
Field "name" should be 100.

  What does psql show if you use it to output the query against that table?

draft=# SELECT column_name, data_type, character_maximum_length,
numeric_precision, table_name FROM information_schema.columns WHERE
column_name = 'name' ORDER BY tabl
e_name;
column_name |     data_type     | character_maximum_length |
numeric_precision |           table_name

draft=#

Query is shorter, but it gives the result of 100.

Let me try the full one from my code...

Thank you.
