*	Remove incorrect comment in dshash.c.	Thomas Munro	2018-10-29
\| \| \| \| \| \| \|	Back-patch to 11. Author: Antonin Houska Discussion: https://postgr.es/m/8726.1540553521%40localhost
*	Minor clean-up in dshash.{c,h}.	Andres Freund	2018-03-01
\| \| \| \| \| \| \| \| \| \|	For consistency with other code that deals in numbers of buckets, the macro BUCKETS_PER_PARTITION should produce a value of type size_t. Also, fix a mention of an obsolete proposed name for dshash.c that appeared in a comment.

*	Fix uninitialized variable in dshash.c.	Andres Freund	2017-09-18
\| \| \| \| \| \| \| \| \| \| \| \|	A bugfix for commit 8c0d7bafad36434cb08ac2c78e69ae72c194ca20. The code would have crashed if hashtable->size_log2 ever had the same value as hashtable->control->size_log2 by coincidence. Per Valgrind.

*	Suppress compiler warnings in dshash.c.	Tom Lane	2017-09-03
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Some compilers complain, not unreasonably, about left-shifting an int32 "1" and then assigning the result to an int64. In practice I sure hope that this data structure never gets large enough that an overflow would actually occur; but let's cast the constant to the right type to avoid the hazard. In passing, fix a typo in dshash.h. Amit Kapila, adjusted as per comment from Thomas Munro. Discussion: https://postgr.es/m/CAA4eK1+5vfVMYtjK_NX8O3-42yM3o80qdqWnQzGquPrbq6mb+A@mail.gmail.com
*	Consolidate the function pointer types used by dshash.c.	Andres Freund	2017-08-24
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Commit 8c0d7bafad36434cb08ac2c78e69ae72c194ca20 introduced dshash with hash and compare functions like DynaHash's, and also variants that take a user data pointer instead of size. Simplify the interface by merging them into a single pair of function pointer types that take both size and a user data pointer. Since it is anticipated that memcmp and tag_hash behavior will be a common requirement, provide wrapper functions dshash_memcmp and dshash_memhash that conform to the new function types.

*	Hash tables backed by DSA shared memory.	Andres Freund	2017-08-22
	Add general purpose chaining hash tables for DSA memory. Unlike DynaHash in shared memory mode, these hash tables can grow as required, and cope with being mapped into different addresses in different backends. There is a wide range of potential users for such a hash table, though it's very likely the interface will need to evolve as we come to understand the needs of different kinds of users. E.g support for iterators and incremental resizing is planned for later commits and the details of the callback signatures are likely to change.
