The issue arises because a dependency, pg_query_go, tries to use the strchrnul() function, which is only available starting from macOS 15.4.

Related discussion and fix in pg_query_go:

• Builds are broken on MacOS 15.4 pganalyze/pg_query_go#132
• Update to libpg_query 17-6.1.0 pganalyze/pg_query_go#134

This has already been addressed in sqldef in the following PR:

• Bump github.com/pganalyze/pg_query_go/v6 from 6.0.0 to 6.1.0 #673

As a result, running
go install github.com/sqldef/sqldef/cmd/psqldef@master
works fine without any issues.

If possible, could you please consider releasing v1.0.7 to include this fix?
It would be greatly appreciated by users who are unable to upgrade their macOS beyond 15.0 at this time.

Thank you very much for your work and for maintaining this excellent project!
