[postgis-devel] gzip support for ST_AsMVT

[Yuri Astrakhan]

Justin, I only saw pglz_compress() as an internal PG function, but it
doesn't appear to be exposed to queries, or is it?  Also, while it appears
to be in the same family of compression algorithms as gzip, I wasn't able
to confirm if standard gzip libraries will be able to decompress it, and if
they can't, it defeats the whole purpose of gzipping tiles - I will need to
uncompress and recompress them as gzips when using/sending to browsers.
