I'm not all that concerned about the names personally, but I want to forestall any temptation for Bruce to start renaming these values later, as he's felt free to do in the past ;-).

You can, but that does not mean that you should. I saw how you'd made the information_schema code induce the value of NAMEDATALEN from type NAME's typlen, and frankly I think it's remarkably ugly and fragile. I do *not* want to recommend that client code do similar things to induce these values. If we do that then we'll be wiring extremely low-level assumptions into client code forevermore. Which of these do you want to support into the indefinite future? current_setting("func_max_args") (SELECT typlen/4 from pg_type where typname = 'oidvector' and typnamespace = (select oid from pg_namespace where nspname = 'pg_catalog')) I realize you think that using GUC variables for this purpose is a bit of a bastardization of the GUC concept, and I can't really argue that it isn't. But the fact is that GUC has succeeded beyond your wildest dreams, and you should not be surprised that people now want to piggyback on all that nice mechanism for other purposes. If we were to invent some other concept for "access to read-only config variables", then we'd just have to duplicate some large fraction of the infrastructure that already exists for GUC.

[shrug] If push comes to shove on a single representation, we will rip out all that int8 stuff and go back to float8. This isn't negotiable; we can't have a system that doesn't have working datetime functionality on a machine without int8.

One could make a good case that INDEX_MAX_KEYS should be exported along with FUNC_MAX_ARGS, rather than letting people write client code that assumes they are the same. I was intending to propose that we also export the following as read-only variables: * NAMEDATALEN * BLCKSZ * integer-vs-float datetime flag (Not sure about suitable GUC names for these --- func_max_args isn't out of line as a GUC name, but surely BLCKSZ is.) NAMEDATALEN is needed for many of the same reasons as FUNC_MAX_ARGS. BLCKSZ is probably useful for pg_autovacuum. The datetime representation flag will be important when people start using binary data transmission seriously --- without it you can't tell what you'll get for a timestamp value. Essentially, these are things we currently tell people to use pg_controldata to find out, but that's quite an inconvenient solution. > While I was in guc.c, I also added short_desc to the definition of the > pg_settings view.
