Critical PostgreSQL-specific fixes identified by database expert review:
1. **Port always passed for localhost** (pg_dump, pg_restore, pg_dumpall, psql)
- Previously, port was only passed for non-localhost connections
- If user has PostgreSQL on non-standard port (e.g., 5433), commands
would connect to wrong instance or fail
- Now always passes -p PORT to all PostgreSQL tools
2. **CREATE DATABASE with encoding/locale preservation**
- Now creates databases with explicit ENCODING 'UTF8'
- Detects server's LC_COLLATE and uses it for new databases
- Prevents encoding mismatch errors during restore
- Falls back to simple CREATE if encoding fails (older PG versions)
3. **DROP DATABASE WITH (FORCE) for PostgreSQL 13+**
- Uses new WITH (FORCE) option to atomically terminate connections
- Prevents race condition where new connections are established
- Falls back to standard DROP for PostgreSQL < 13
- Also revokes CONNECT privilege before drop attempt
4. **Improved globals restore error handling**
- Distinguishes between FATAL errors (real problems) and regular
ERROR messages (like 'role already exists' which is expected)
- Only fails on FATAL errors or psql command failures
- Logs error count summary for visibility
5. **Better error classification in restore logs**
- Separate log levels for FATAL vs ERROR
- Debug-level logging for 'already exists' errors (expected)
- Error count tracking to avoid log spam
These fixes improve reliability for enterprise PostgreSQL deployments
with non-standard configurations and existing data.
