tsloughter/pg_types

This system is an Erlang library named pg\_types that provides an OTP-based interface for encoding and decoding PostgreSQL data types. It supports a wide range of basic, composite, and geometric types, including configurable handling for enums, JSON, and timestamps. The library manages type metadata via ETS tables and includes comprehensive test coverage for its codec implementations.

The include directory now contains pg\_types.hrl, which defines the \#type\_info record used to store PostgreSQL type metadata. This record includes fields for OID, module, configuration, pool, name, send/receive functions, length, input/output functions, element OID, base OID, and component OIDs/types, providing the structural basis for type handling in the application.

This release adds the core type-handling modules for the \pg\_types\ library, enabling the encoding and decoding of a wide range of PostgreSQL data types. The new modules cover basic types (int2, int4, int8, float4, float8, boolean, date, time, timestamp, timestamptz, interval, oid, name, bit\_string, macaddr), composite and complex types (array, record, range, hstore, json, jsonb, tsvector), and geometric types (point, line, line\_segment, path, polygon, circle). It also introduces support for infinity and NaN values in floating-point types, configurable enum encoding/decoding (including atom support), and configurable JSON library integration for json/jsonb types.

The library has been renamed from epq\_datatypes to pg\_types and now provides an OTP-based interface for encoding and decoding PostgreSQL data types. Users can now configure enum handling to convert values to atoms (including existing atoms), return timestamps as Erlang system time, and use the new \pg\_types:update/3\ API to populate type information into an ETS table. The update also adds support for new data types including tsvector, tid, bit\_string, records/composite types, and geometric types (circle, line, line\_segment, path, polygon).

(repo-wide) · high confidence

Added comprehensive test coverage for the library's encoding and decoding logic across a wide range of PostgreSQL data types. The new test suite includes property-based tests (using the Proper library) for binary, boolean, float (including NaN and infinity), geometry (point, line, path, polygon, circle), hstore, IP addresses (IPv4/IPv6 and CIDR), integers (16/32/64-bit), JSON/JSONB (including custom compressed configurations), MAC addresses, names, time, timestamps, timestamp with time zones (including UTC offset handling), tsvector, and UUIDs (binary, string, and integer formats). Additionally, unit tests were added to verify specific timestamp with time zone offset conversions.
