Stack overflow with Postgres in v1.31.x #7699
Description
Description
When using gorm v1.31.0 or v1.31.1 with PostgreSQL, certain queries cause a stack overflow (infinite recursion). The issue does not occur with MySQL or SQLite, only PostgreSQL.
Steps to reproduce
- Use gorm v1.31.0 or v1.31.1 with
gorm.io/driver/postgres - Run queries that involve DELETE with WHERE clause
Stack trace
