Prepared Statements integration in PsycoPG - Mailing list psycopg

Hi all:

I'm trying to integrate the PQprepare and PQexecPrepared methods of libpq in the psycopg, but i'm not sure what API must have in python.

My initial idea is two new methods on the cursor class:

  * prepare(statement_name, statement_query)

  * execPrepared(statement, values)

This have some extra problems like knowing the number and type of attributes expected by prepare and execPrepared, needed by the PQprepare and PQexecPrepared. One option is to add and extra parameter that receive this information, another way is parse the statement_query to extract this information, but probably must be a simplified versión of this (force types like TEXT to not explicitly defined types).

Probably another option is take the same solution to the PQexecParams.

Any idea about this? Any suggestion?

Greetings and thanks.
