Re: [HACKERS] Regarding GSoc Application

Hi John,

Yes,I agree,that can be done,but we had an extensive discussion on it
yesterday and Andrew and Tom believe that would pose serious security issues
as any malicious user can change the arguments sent to the SQL and cause
problems.

PL/Java also provides for passing SQL arguments in various data types
to/from your java code. not usinig pl/java would mean you'd have to
reinvent all those wheels, they exist now in a standard mannner, why not
use them?

as I see it, your proposal could be implemented as a set of pljava
functions callable from SQL that would in turn invoke JDBC to connect to
and fetch data from your foreign database, then return it to the calling
SQL procedure, much as dblink does now for pg to pg database links.
