I am confused what the "server/" prefix means in a path name.

We currently say:

	The <acronym>OID</acronym>s of the built-in data types are defined in
	the file <filename>src/include/catalog/pg_type_d.h</filename> in the
	source tree.

We could add "compiled":

	The <acronym>OID</acronym>s of the built-in data types are defined in
	the file <filename>src/include/catalog/pg_type_d.h</filename> in the
	source tree after it is compiled.
