[postgis-devel] RE: pgxs

[alex bodnaru]

hi friends,

the making system i was talking about was good for pgsql 7.2, 7.4, 8.0
at least.

the more general pgxs aproach may be used as a model, but it should be
necessary, to my opinion, just for makefile.shlib, because the variables
in makefile.global are easy to determin from pg_config.

regards,

alex
