Tom Lane 9cbaf72177 In the continuing saga of FE/BE protocol revisions, add reporting of ... initial values and runtime changes in selected parameters. This gets rid of the need for an initial 'select pg_client_encoding()' query in libpq, bringing us back to one message transmitted in each direction for a standard connection startup. To allow server version to be sent using the same GUC mechanism that handles other parameters, invent the concept of a never-settable GUC parameter: you can 'show server_version' but it's not settable by any GUC input source. Create 'lc_collate' and 'lc_ctype' never-settable parameters so that people can find out these settings without need for pg_controldata. (These side ideas were all discussed some time ago in pgsql-hackers, but not yet implemented.)		2003-04-25 19:45:10 +00:00
