Dear patchers,

Following the discussion about previous versions of this patch, please
find attached a new patch candidate for warning about costly foreign key
referential integrity checks.

1/ it generates a WARNING

2/ it DETAILs the attributes and types

3/ some regression tests are also appended to foreign_key.sql

It validates for me against current "head".

Have a nice day,

TIP 9: the planner will ignore your desire to choose an index scan if your
      joining column's datatypes do not match
