>X+**  Originally written by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
>X+**  Rich $alz is now <rsalz@bbn.com>.
>X+**  Special thanks to Lars Mathiesen <thorinn@diku.dk> for the LABORT code.
>X+**
>X+**  This code was shamelessly stolen from the "pql" code by myself and
>X+**  slightly modified :)
>X+**
>X+**  All references to the word "star" were replaced by "percent"
>X+**  All references to the word "wild" were replaced by "like"
>X+**
>X+**  All the nice shell RE matching stuff was replaced by just "_" and "%"
>X+**
>X+**  As I don't have a copy of the SQL standard handy I wasn't sure whether
>X+**  to leave in the '\' escape character handling.
>X+**
>X+**  Keith Parks. <keith@mtcc.demon.co.uk>
>X+**
>X+**  SQL92 lets you specify the escape character by saying
>X+**  LIKE <pattern> ESCAPE <escape character>. We are a small operation
>X+**  so we force you to use '\'. - ay 7/95
>X+**
>X+**  Now we have the like_escape() function that converts patterns with
>X+**  any specified escape character (or none at all) to the internal
>X+**  default escape character, which is still '\'. - tgl 9/2000
>X+**
>X+** The code is rewritten to avoid requiring null-terminated strings,
>X+** which in turn allows us to leave out some memcpy() operations.
>X+** This code should be faster and take less memory, but no promises...

>X+ * For example consider

>X+ * We don't want to add new clauses to baserestrictinfo, just
>X+ * use it as index quals.
>X+ *
>X+ * Next thing which it possible to test is use append of

>X+ * For example consider
>X+ *	WHERE ( a.x=5 and a.y>10 ) OR a.x>6

>X+ *		Index Scan (a.x=5)	--in case of index on (a.x)
>X+ *		Index Scan (a.x>6)
>X+ * For that we should proof that index quals isn't overlapped,

>X+Plantuner - enable planner hints
>X+
>X+   contrib/plantuner is a contribution module for PostgreSQL 8.4+, which
>X+   enable planner hints.
>X+
>X+   All work was done by Teodor Sigaev (teodor@sigaev.ru) and Oleg Bartunov
>X+   (oleg@sai.msu.su).
>X+
>X+   Sponsor: Nomao project (http://www.nomao.com)
>X+
>X+Motivation
>X+
>X+   Whether somebody think it's bad or not, but sometime it's very
>X+   interesting to be able to control planner (provide hints, which tells
>X+   optimizer to ignore its algorithm in part), which is currently
>X+   impossible in POstgreSQL. Oracle, for example, has over 120 hints, SQL
>X+   Server also provides hints.
>X+
>X+   This first version of plantuner provides a possibility to hide
>X+   specified indexes from PostgreSQL planner, so it will not use them.
>X+
>X+   There are many situation, when developer want to temporarily disable
>X+   specific index(es), without dropping them, or to instruct planner to
>X+   use specific index.
>X+
>X+   Next, for some workload PostgreSQL could be too pessimistic for
>X+   newly created tables and assumes much more rows in table than
>X+   it actually has. If plantuner.fix_empty_table GUC variable is set
>X+   to true then module will set to zero number of pages/tuples of
>X+   table which hasn't blocks in file.
>X+
>X+Installation
>X+
>X+     * Get latest source of plantuner from CVS Repository
>X+     * gmake && gmake install && gmake installcheck
>X+
>X+Syntax
>X+	plantuner.forbid_index (deprecated)
>X+	plantuner.disable_index
>X+		List of indexes invisible to planner
>X+	plantuner.enable_index
>X+		List of indexes visible to planner even they are hided
>X+		by plantuner.disable_index. 
>X+
>X+Usage
>X+
>X+   To enable the module you can either load shared library 'plantuner' in
>X+   psql session or specify 'shared_preload_libraries' option in
>X+   postgresql.conf.
