erleans/pgo

PGo is an Erlang library that serves as a PostgreSQL client and connection pool manager. It provides core database operations including query execution, transaction management, and SSL/TLS authentication, while supporting advanced features like LISTEN/NOTIFY and dynamic row decoding. The system integrates OpenTelemetry for distributed tracing and includes comprehensive test coverage for connection lifecycle and data type handling.

Introduces the pgo library, a Postgres client and connection pool for Erlang. This release adds core functionality for establishing connections, executing queries and transactions, and managing a connection pool. It includes support for SSL/TLS connections, SCRAM-SHA-256 authentication, and OpenTelemetry-based tracing. The library also provides features such as LISTEN/NOTIFY support, dynamic password functions, and configurable row decoding options (maps vs tuples).

The project has replaced the \sbroker\ and \pgsql\ dependencies with \backoff\, \pg\_types\ (0.6.0), and \opentelemetry\_api\ (1.5). This shift simplifies pool configuration by removing the \workers\ parameter and adopting a default pool name of \pgo\_default\. Additionally, the project license has been updated from BSD to Apache 2.0, and the README has been rewritten to reflect the new API and OpenTelemetry integration.

(repo-wide) · high confidence

The configuration structure has been updated to use the \pgo\ application instead of the previous \pgsql\_pool\ for database connection management, with the default pool now set to a size of 5. Additionally, the example configuration now includes a default kernel logger setup that outputs debug-level messages in a single-line format, ensuring consistent logging behavior out of the box.

Added test SSL certificates for server authentication; Expanded Common Test suite for connection pooling, types, and tracing.

Added a new \doc/overview.edoc\ file that introduces the PGo PostgreSQL client library. The documentation explains the library's design philosophy (direct socket usage, binary protocol), lists system requirements (Erlang/OTP 20+), and provides usage examples for configuring and starting connection pools via application environment or supervisor trees. It also details configuration options for database connections, pool behavior, and query execution, as well as integration with Telemetry and OpenCensus for tracing.
