  1. Add new keywords SNAPSHOT and TYPES to the keyword list in gram.y

  1. pgsql: Add new keywords SNAPSHOT and TYPES to the keyword list in gram.

    Heikki Linnakangas <heikki.linnakangas@iki.fi> — 2012-02-09T09:42:12Z

    Add new keywords SNAPSHOT and TYPES to the keyword list in gram.y

These were added to kwlist.h as unreserved keywords in separate patches,
but authors forgot to add them to the corresponding list in gram.y.
Because of that, even though they were supposed to be unreserved keywords,
they could not be used as identifiers. src/tools/check_keywords.pl is your
friend.

I wondered a couple of weeks ago if we could, instead, generate the
lists in gram.y from kwlist.h.

We've looked into that in the past.  bison does not seem to have any
sort of "include" directive, which means the only way to do it would be
to have the gram.y file be built from pieces at compile time.  Although
Michael is successfully doing something of the sort for ecpg, I find it
way too ugly in return for the amount of benefit we'd get.

If people are sufficiently worried about this, a better answer would be
to teach the makefiles to run check_keywords.pl during every build.

Doh, bummer.

Agreed.

FWIW that script is throwing a warning here:
Use of assignment to $[ is deprecated at /pgsql/source/HEAD/src/tools/check_keywords.pl line 19.

Also, we should at least do the attached to simplify the process.

Any Perl hackers want to improve that script?

Actually, what would make sense in that line is to attach it to the
existing maintainer-check target, no?  I don't think top-level
"make check" descends into this directory.

The attached 2 liner does it for me.

I have hooked this into maintainer-check now.
