greenplumn fmgrtab_mock 代码
文件路径：/src/test/unit/mock/fmgrtab_mock.c
/*
* This is a mock version of src/backend/utils/fmgrtab.c. The real fmgrtab.c
* contains a large table, fmgr_builtins, which contains a pointer to all
* the built-in functions that are exposed at SQL-level, in the pg_proc
* catalog. We don't need the table in mock tests, and if we leave them out,
* we don't need to link in the .o files containing them, which helps to cut
* down the size of the test programs.
