Re: Problem with getImportedKeys / getExportedKeys - Mailing list pgsql-jdbc

Hi Bruce,

Can we get this tested and committed before RC1 is released?

All of the Database Admin/Management tools out there which use JDBC and
support RI need this in order to work correctly.

Making a point of it as I think it's pretty important.

:-)

Regards and best wishes,

Justin Clift
