— C Macro: PQsetdb

PostgreSQL documentation says:

It is provided for backward compatibility with very old programs.

Since no one has asked for it in Guile-PG, we assume no such programs exist.

— C Function: PQconnectStart
— C Function: PQconnectPoll
— C Function: PQresetStart
— C Function: PQresetPoll

Laziness, pure and simple.

— C Function: PQstatus

More laziness. Since we have pg-reset, we have the proper mechanism for dealing with PQstatus values other than CONNECTION_OK.

— C Function: PQsocket

Unlikely to be useful.

— C Function: PQgetssl

We'll get to SSL support one of these days.

— C Function: PQresStatus
— C Function: PQclear
— C Function: PQmakeEmptyPGresult
— C Function: PQcmdStatus

Unlikely to be useful.

— C Function: PQoidStatus

PosgreSQL documentation says:

This function is deprecated in favor of PQoidValue. It is not thread-safe.

— C Function: PQescapeString
— C Function: PQescapeBytea

Deprecated in favor of PQescapeStringConn and PQescapeByteaConn, respectively.

— C Function: PQfreemem

Internal (I think).

— C Function: PQfn

PostgreSQL documentation says:

Tip: This interface is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.

— C Function: PQputnbytes

This is in the section “Obsolete Functions for COPY”.

— C Function: PQsetNoticeReceiver
— C Function: PQsetNoticeProcessor

We provide the schemified interface pg-set-notice-out!.
