Re: [HACKERS] GSoC 2017: Foreign Key Arrays

Looking at 0001+0003, I see it claims GIN support for <<@ and @>>, but
actually only the former is implemented fully; the latter is missing a
strategy number in ginarrayproc.c and pg_amop.dat, and also
src/test/regress/sql/gin.sql does not test it.  I suspect
ginqueryarrayextract needs to be told about this too.
