There was some previous discussion of whether DBD:pg should continue using libpq or implement the wire protocol in Perl, and whether ODBC should move to using libpq.
I think we should favor libpq usage wherever possible and only re-implement it in the native language when required, like for jdbc/java. I think having all interfaces take advantage of libpq improvements and features is a major win. If we need to add things to libpq to make it easier, fine, but that is minor work compared to maintaining separate wire protocol for each interface language. --------------------------------------------------------------------------- Tom Lane wrote: > Oliver Jowett <[EMAIL PROTECTED]> writes: > > Tom reckons that PREPARE (at the SQL level) taking unknown types is not > > useful as there is no feedback mechanism along the lines of the V3 > > protocol Describe messages to let the client find out what types were > > inferred by the PREPARE. > > > I am saying this doesn't matter as the client can still use the > > resulting statement just fine without knowing the types.
