## 0.10.0 (2018-06-27)
|
||||
|
||||
**High-level changes**
|
||||
* Planning time improvement (**up to 15x**) when a hypertable has many chunks by only expanding (and taking locks on) chunks that will actually be used in a query, rather than on all chunks (as was the default PostgreSQL behavior).
|
||||
* Smarter use of HashAggregate by teaching the planner to better estimate the number of output rows when using time-based grouping.
|
||||
* New convenience function for getting the approximate number of rows in a hypertable (`hypertable_approximate_row_count`).
|
||||
* Fixed support for installing extension into non-`public` schemas
|
||||
* Other bug fixes and refactorings.
|
||||
|
||||
**Notable commits**
|
||||
* [12bc117] Fix static analyzer warning when checking for index attributes
|
||||
* [7d9f49b] Fix missing NULL check when creating default indexes
|
||||
* [2e1f3b9] Improve memory allocation during cache lookups
|
||||
* [ca6e5ef] Fix upserts on altered tables.
|
||||
* [2de6b02] Add optimization to use HashAggregate more often
|
||||
* [4b4211f] Fix some external functions when setting a custom schema
|
||||
* [b7257fc] Optimize planning times when hypertables have many chunks
|
||||
* [c660fcd] Add hypertable_approximate_row_count convenience function
|
||||
* [9ce1576] Fix a compilation issue on pre 9.6.3 versions
|
||||
|
||||
**Thanks**
|
||||
* @viragkothari for suggesting the addition of `hypertable_approximate_row_count` and @fvannee for providing the initial SQL used to build that function
|
||||
* 'mintekhab' from Slack for reporting a segfault when using upserts on an altered table
|
||||
* @mmouterde for reporting an issue where the extension implicitly expected to be installed in the `public` schema
|
||||
* @mfuterko for bringing some potential bugs to our attention via static analysis
