* fix(filer/postgres): default to ON CONFLICT upsert to keep tx alive A KvPut from the inode-index secondary write could fail with 23505 (duplicate key) inside a rename's transaction, after which the next statement returned 25P02 and rename surfaced to FUSE as EIO. Default the postgres upsert query when enableUpsert=true so INSERTs are idempotent; the enableUpsert=false escape hatch is preserved for non-PG-compatible backends. * fix(filer/mysql): default to ON DUPLICATE KEY UPDATE upsert Same shape as the postgres default: when enableUpsert=true but no upsertQuery is configured, install a sensible default so the inode-index KvPut does not waste a duplicate-key roundtrip on every entry write. Uses the VALUES() form so the default works on MariaDB and MySQL >=5.7; the MySQL 8.0.19 row-alias form is left to explicit config. * fix(filer): default enableUpsert=true for sql stores The default-template fallback only kicks in when enableUpsert=true, so minimal configs that omit the flag entirely were still exposed. Default it on for postgres/postgres2/mysql/mysql2; an explicit false in filer.toml still wins because SetDefault only fills absent keys.
