This is a pure refactoring commit: there isn't (I hope) any functional change. StoreAttrDefault and RemoveAttrDefault[ById] are moved from heap.c, reducing the size of that overly-large file by about 300 lines. I took the opportunity to trim unused #includes from heap.c, too. Two new functions for translating between a pg_attrdef OID and the relid/attnum of the owning column are created by extracting ad-hoc code from objectaddress.c. This already removes one copy of said code, and a follow-on bug fix will create more callers. The only other function directly manipulating pg_attrdef is AttrDefaultFetch. I judged it was better to leave that in relcache.c, since it shares special concerns about recursion and error handling with the rest of that module.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
