The t_iseq() macro does not need to be guarded by a character length check (at least when the comparison value is an ASCII character, as its documentation requires). Some portions of contrib/ltree hadn't read that memo, so simplify them. The last change in gettoken_query, - else if (charlen == 1 && !t_iseq(state->buf, ' ')) + else if (!t_iseq(state->buf, ' ')) looks like it's actually a bug fix: I doubt that the intention was to silently ignore multibyte characters as if they were whitespace. I'm not tempted to back-patch though, because this will have the effect of tightening what is allowed in ltxtquery strings. Discussion: https://postgr.es/m/2548310.1664999615@sss.pgh.pa.us
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.
