Fix: PostgreSQL expert review - cluster backup/restore improvements

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.
