version 1.1.0

New features:

• add support for hypothetical indexes on expression
• add a hypopg_get_indexdef() function to get definition of a stored
  hypothetical index

Bug fixes:

• don't allow hypothetical unique or multi-column index if the AM doesn't
  support it
• disallow hypothetical indexes on system columns (except OID)
• fix indexes using DESC clause and default NULLS ordering, thanks to
  Andrew Kane for the report and test case.
• fix PostgreSQL 9.6+ support, thanks to Rob Stolarz for the report

Miscellaneous:

• add support for PostgreSQL 10

version 1.0.0

hypopg is now stable.

Bug fix:

• fix a memory leak in hypopg() function

version 0.0.5

New features:

• add support for PostgreSQL 9.6, thanks to Konstantin Mosolov for fixing some
  issues
• add support from new bloom access method (9.6+)

Bug fixes:

• fix issue with hypothetical indexes on expression (thanks to Konstantin
  Mosolov)
• fix possible crash in hypothetical index size estimation
• fix compatibility with pg 9.4-

version 0.0.4

New features:

• add support for BRIN indexes (for pg 9.5+ obviously).
• handle index on predicate.
• handle index storage parameters for supported index methods. For now, this means :
  • fillfactor for btree indexes
  • pages_per_range for brin indexes

Bug fixes or improvements:

• check that number of column is suitable for a real index
• free memory when hypothetical index creation fails
• for btree indexes, check that the estimated average row size is small enough to allow a real index creation.
• safer handling of locks.

Misc:

• remove the simplified "hypopg_add_index()" function

version 0.0.3

• fix a bug when a regular query could fail after a hypothetical index have been created, and tested with explain.
• hypopg_create_index() and hypopg_add_index() now returns the oid and index names.
• add hypopg.enabled GUC. It allows disabling HypoPG globally or in a single backend. Thanks to Ronan Dunklau for the patch.

version 0.0.2

Fix https://github.com/dalibo/hypopg/issues/1 : server crash when trying to create an hypothetical functional index.

version 0.0.1

First version of HypoPG.

Only simple hypothetical btree indexes are handled.
