init options of the template as top-level options in the syntax. This also
makes ALTER a bit easier to use, since options can be replaced individually.
I also made these statements verify that the tmplinit method will accept
the new settings before they get stored; in the original coding you didn't
find out about mistakes until the dictionary got invoked.
Under the hood, init methods now get options as a List of DefElem instead
of a raw text string --- that lets tsearch use existing options-pushing code
instead of duplicating functionality.
'with map' parameter; as things now stand there's really not much point
in specifying a config-to-copy if you don't copy its map. Also, use
COPY instead of TEMPLATE as the key word for a config-to-copy, so as
to avoid confusion with text search templates. Per discussion; the
just-committed reference page for the command already describes it
this way.
Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing,
so anything that's broken is probably my fault.
Documentation is nonexistent as yet, but let's land the patch so we can
get some portability testing done.
