pgsql: Define pg_attribute_cold and pg_attribute_hot macros - Mailing list pgsql-committers

Define pg_attribute_cold and pg_attribute_hot macros

For compilers supporting __has_attribute and __has_attribute (hot/cold).

__has_attribute is supported on gcc >= 5, clang >= 2.9 and icc >= 17.

A followup commit will implement some usages of these macros.
