PostgreSQL types based on _Decimal32 and _Decimal64 types.
I wrote this library due performance comparation with PostgreSQL's Numeric type. I would to know how much big impact has fact, so Numeric is varlena type. This initial implementation is based on basic _Decimal support, that is not complete (and check of overflow is slower, than could be with better library). This library contains some basic arithmetic operators and basic casts.
postgres=# CREATE EXTENSION decimal; CREATE EXTENSION postgres=# SELECT 3.14::decimal32; decimal32 ─────────── 3.14 (1 row) postgres=# SELECT 3.14::decimal64; decimal64 ─────────── 3.14 (1 row)
