pgman v0.4.1

Fixed

• Slow queries work on PostgreSQL 12, which names pg_stat_statements'
  times total_time and mean_time.
• Masked dumps work on PostgreSQL 10 and 11.
• A restore into a database it created counts "already exists" from
  the new database's template as harmless and names it, instead of
  saying the database wasn't empty: every restore into YugabyteDB
  exited 1 for its own foreign server.
• The schema wizard and schema_lint leave alone what is in a schema
  an extension made, such as TimescaleDB's chunks.
• A masked dump of a database with TimescaleDB hypertables stops and
  names them, instead of restoring them as plain tables without the rows
  of their compressed chunks.
• The schema wizard's "foreign key without an index" (LINT101) no
  longer flags a key whose column leads an index: it read the index's
  second column.
