# Doltgres Reaches 99% Compliance on SQL Logic Tests

**[DoltHub Blog](https://daily.dev/sources/dolthub-blog)** · 6 min read · 0 upvotes · 0 comments

## Summary

Doltgres, the version-controlled PostgreSQL-compatible database, has reached 99% compliance on its SQL Logic Test suite — a key milestone on the road to the Doltgres 1.0 release planned for August 6th. The team first established a baseline by running the test suite against stock PostgreSQL, discovering that many failures were due to SQLite/MySQL assumptions baked into the test runner rather than actual Doltgres bugs. Fixes included handling integer vs. float type differences, empty result sets, Postgres-specific type names, and MySQL-only statements. Parallelizing the test runner also dramatically reduced iteration time. The most notable real bug found was in the COALESCE() implementation, which was using incorrect type conversion for mixed numeric types instead of Postgres' assignment cast rules. With correctness now checked off, the team is on track for the August 6th 1.0 launch.
