Work with rust-postgres type converters?

[bluejekyll]

For example:
https://github.com/sfackler/rust-postgres/blob/master/postgres-protocol/src/types.rs

It would be neat to try and reuse those type conversions for PgDatum's. Though they are BigEndian, whereas PgDatum is NativeEndian.

Please consider also integrating postgis types.
Like these:

https://crates.io/crates/postgis

I think that would a great addition. It would probably need to be optional, as it would require the postgis extension to be installed.

I think that could be a separate issue.
