Previously, this code just smashed all types of DefElem values to strings, cavalierly reasoning that nobody would care. But in point of fact, most of the defGetFoo functions do distinguish among different input syntaxes; for instance defGetBoolean will accept 1 as an integer but not "1" as a string. This led to CREATE/ALTER TEXT SEARCH DICTIONARY accepting 0 and 1 as values for boolean dictionary properties, only to have the dictionary fail at runtime. We can upgrade this behavior by teaching serialize_deflist that it does not need to quote T_Integer or T_Float nodes' values on output, and then teaching deserialize_deflist to restore unquoted integer or float values as the appropriate node type. This should not break anything using pg_ts_dict.dictinitoption, since that field is just defined as being something valid to include in CREATE TEXT SEARCH DICTIONARY. deserialize_deflist is also used to parse the options arguments for the ts_headline family of functions, but so far as I can see this won't cause any problems there either: the only consumer of that output is prsd_headline which always uses defGetString. (Really that's a bad idea, but I won't risk changing it here.) This is surely a bug fix, but given the lack of field complaints I don't think it's necessary to back-patch.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
