Yet there is ONE file (src\backend\parser\gram.h) that goes into the server directory (postgresql\include\server\parser\gram.h)which has a Bison exception in its license that might affect everything that isdelivered with this file. The exception says: Bison Exception: "As a special exception, you may create a larger work that contains part or all of the Bison parser skeleton and distributethat work under terms of your choice, so long as that work isn't itself a parser generator using the skeleton ora modified version thereof as a parser skeleton. Alternatively, if you modify or redistribute the parser skeleton itself,you may (at your option) remove this special exception, which will cause the skeleton and the resulting Bison outputfiles to be licensed under the GNU General Public License without this special exception." So my understanding is that I must take this file out from the deliverable. Isn't that correct?

No, it isn't.
If you were to generate Postgres' grammar with a custom-modified Bison,
then this wording might require you to honor GPL as well as BSD terms
of distribution for the result. Nobody does that though. Per the
above statement, we can distribute the files generated by stock versions
of Bison under terms of our choice, to wit the Postgres license.
Were this not the case, we wouldn't be using Bison.
