OK, I'll make that happen.

Hmm ... I suppose, but I'd still prefer that the option names didn't
include the word "file".
Also, while revising the reference pages for the syntax changes I made,
I realized that there's further simplification possible for the
dictionary commands. I changed these commands to use the same
"definition list" construct that's used by CREATE OPERATOR and such.
It has the nice property that the option "keywords" aren't actually
keywords in the eyes of the grammar, they're just any identifiers.
So what we have got as of CVS HEAD is
CREATE TEXT SEARCH DICTIONARY name (
TEMPLATE = template
[, OPTION = init_options ]
ALTER TEXT SEARCH DICTIONARY name (
OPTION = init_options
where "init_options" is supposed to be a string literal containing stuff
When you look at it, this is downright silly. Why don't we flatten
the two levels together and write something like
CREATE TEXT SEARCH DICTIONARY swedish (
TEMPLATE = snowball,
LANGUAGE = swedish,
STOPWORDS = swedish
The original implementation couldn't do that but it's easy in the
definition-list grammar. This is even more useful for ALTER, because
it'd be possible to change the value of one option without having to
write out the values of all the others. What I'd suggest is that
we adopt the convention that an option is dropped if its name appears
with no value, otherwise it's kept unless overridden with a new value.
ALTER TEXT SEARCH DICTIONARY swedish (
this dictionary would have LANGUAGE = swedish and no stopwords option.
Any objections to changing it like that?
