pgsql: Remove unnecessary array object_classes[] in dependency.c

Remove unnecessary array object_classes[] in dependency.c object_classes[] provided unnecessary indirection between catalog OIDs and the enum ObjectClass when calling add_object_address(). This array has been originally introduced in 30ec31604d5 and was useful because not all relation OIDs were

pgsql: Adjust memory allocation functions to allow sibling calls

Adjust memory allocation functions to allow sibling calls Many modern compilers are able to optimize function calls to functions where the parameters of the called function match a leading subset of the calling function's parameters. If there are no instructions in the calling function after the

pgsql: Use NULL instead of 0 for 'arg' argument in dshash_create() call

Use NULL instead of 0 for 'arg' argument in dshash_create() calls. A couple of dshash_create() callers provide 0 for the 'void *arg' argument, which might give readers the incorrect impression that this is some sort of "flags" parameter. Reviewed-by: Andy Fan Discussion:

pgsql: Add helper functions for dshash tables with string keys.

Add helper functions for dshash tables with string keys. Presently, string keys are not well-supported for dshash tables. The dshash code always copies key_size bytes into new entries' keys, and dshash.h only provides compare and hash functions that forward to memcmp() and tag_hash(), both of

pgsql: Group more closely cache updates for backends in sequence.c

Group more closely cache updates for backends in sequence.c Information of sequences is cached for each backend for currval() and nextval(), and the update of some cached information was mixed in the middle of computations based on the other properties of a sequence, for the increment value in
