Changelog

Fixed

  • Wait for further data from the network in pg-read-chars if the process buffer doesn't yet contain the necessary data (fix from swilsons).

[0.19] - 2022-11-19

New

  • Add support for parsing the BIT and VARBIT datatypes.
  • Add support for parsing ARRAY datatypes.
  • Add support for parsing RANGE datatypes (integer and numerical).
  • Add support for parsing HSTORE datatypes (see function pg-hstore-setup to prepare the database connection for use of the HSTORE datatype).
  • Add function pg-cancel to request cancellation of the command currently being processed by the backend.

Fixed

  • Fix bug in handling of DataRow messages when zero columns returned by query.

[0.18] - 2022-10-16

New

  • Add support for connecting to PostgreSQL over a local Unix socket.
