I would call it Advanced advance :)
How do you plan to connect to any database? Using which drivers? Is this why
you mention ODBC? But ODBC has its own virtual types. Is it reliable? And
not all Oracle database have ODBC (you must pay for it). Just for
information, can you describe in more details?
A good start might be to be able to read the dumps from Oracle, MySQL, DB2 and
MsSQL. This would be a small revolution for PostgreSQL and would suit 90%
needs of users. When this is achieved, and only then, you would go for more
complex things.
I feel (but I am only an average programmer as you know) that a series of
regexp would suffice.
Cheers, Jean-Michel
