pgquarrel vs Redgate Schema Compare for Oracle

pgquarrel compares PostgreSQL database schemas and produces SQL commands to bring a target schema in line with a source. It connects to PostgreSQL servers and reads catalog metadata directly, rather than depending on tools such as pg_dump. The project describes deploying schema changes to testing, staging, or production as its main use. Filters can narrow comparisons to selected object types or include and exclude schemas by pattern. Output goes to stdout by default, with options to save it to a file, print a summary, or place changes in one transaction. pgquarrel does not manipulate table data with INSERT, UPDATE, DELETE, or COPY. Its documented object coverage includes both complete and partial support; inheritance and roles are noted absences, and not all PostgreSQL objects are supported. Output may not work as expected when the source PostgreSQL version is newer than the target. The software is free under the BSD-3-Clause license, distributed as source through GitHub or a Git clone, and the listed latest release is 0.7.0.
