common/jsonapi: support libpq as a client
Based on a patch by Michael Paquier.For libpq, use PQExpBuffer instead of StringInfo. This requires us totrack allocation failures so that we can return JSON_OUT_OF_MEMORY asneeded rather than exit()ing.Author: Jacob Champion <jacob.champion@enterprisedb.com>Co-authored-by: Michael Paquier <michael@paquier.xyz>Co-authored-by: Daniel Gustafsson <daniel@yesql.se>Reviewed-by: Peter Eisentraut <peter@eisentraut.org>Discussion:https://www.postgresql.org/message-id/flat/d1b467a78e0e36ed85a09adf979d04cf124a9d4b.camel@vmware.com
