This commit comes as a continuation of the discussion that has led to d522b05, as \v was handled inconsistently when parsing array values or anything going through the parsers, and changing a parser behavior in stable branches is a scary thing to do. The parsing of array values now uses the more central scanner_isspace() and array_isspace() is removed. As pointing out by Peter Eisentraut, fix a confusing reference to horizontal space in the parsers with the term "horiz_space". \f was included in this set since 3cfdd8f from 2000, but it is not horizontal. "horiz_space" is renamed to "non_newline_space", to refer to all whitespace characters except newlines. The changes impact the parsers for the backend, psql, seg, cube, ecpg and replication commands. Note that JSON should not escape \v, as per RFC 7159, so these are not touched. Reviewed-by: Peter Eisentraut, Tom Lane Discussion: https://postgr.es/m/ZJKcjNwWHHvw9ksQ@paquier.xyz
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.
