file01= 7 columns, row unknown (but few)
file02= 7 columns, row unknown (but many)

e.g.
file 01

DROP FOREIGN TABLE(7) PostgreSQL 9.2.7 Documentation DROP FOREIGN TABLE(7)NAME
DROP_FOREIGN_TABLE - remove a foreign table
SYNOPSIS
DROP FOREIGN TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP FOREIGN TABLE removes a foreign table. Only the owner of a foreign table can remove it.
PARAMETERS
IF EXISTS
Do not throw an error if the foreign table does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of the foreign table to drop.
CASCADE
Automatically drop objects that depend on the foreign table (such as views).
RESTRICT
Refuse to drop the foreign table if any objects depend on it. This is the default.
EXAMPLES
To destroy two foreign tables, films and distributors:
DROP FOREIGN TABLE films, distributors;
COMPATIBILITY
This command conforms to the ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command,
and apart from the IF EXISTS option, which is a PostgreSQL extension.
