Transpose rows to column in postgresql

The following query gives me a list of 1222 distinct columns:

select distinct column_name from information_schema.columns where table_name like 'fea_var%';

I want to create one base table which has all the 1222 rows from this query as columns. fea_var% tables are just empty tables with columns. So, the output should be an empty table with those 1222 columns.
