Hmm... the buildfarm member prairiedog doesn't like this change. Because
pg_lzcompress.c uses the macros (like VARSIZE) for varlena datatypes which
are defined in postgres.h which client-side should not include. ISTM that
pg_lzcompress.c should be changed to be "varlena-free", in order to push it
in src/common.
