-Array iterator functions, by Massimo Dal Zotto <dz@cs.unitn.it>

-
-This loadable module defines a new class of functions which take
-an array and a scalar value, iterate a scalar operator over the
-elements of the array and the value, and compute a result as
-the logical OR or AND of the iteration results.
-For example array_int4eq returns true if some of the elements
-of an array of int4 is equal to the given value:
-
-	array_int4eq({1,2,3}, 1)  -->  true
-	array_int4eq({1,2,3}, 4)  -->  false
-
-If we have defined T array types and O scalar operators we can
-define T x O x 2 array functions, each of them has a name like
-"array_[all_]<basetype><operation>" and takes an array of type T
-iterating the operator O over all the elements. Note however
-that some of the possible combination are invalid, for example
-the array_int4_like because there is no like operator for int4.
-
-We can then define new operators based on these functions and use
-them to write queries with qualification clauses based on the
-values of some of the elements of an array.
-For example to select rows having some or all element of an array
-attribute equal to a given value or matching a regular expression:
-
-	create table t(id int4[], txt text[]);
-
-	-- select tuples with some id element equal to 123
-	select * from t where t.id *= 123;
-
-	-- select tuples with some txt element matching '[a-z]'
-	select * from t where t.txt *~ '[a-z]';
-
-	-- select tuples with all txt elements matching '^[A-Z]'
-	select * from t where t.txt[1:3] **~ '^[A-Z]';
-
-The scheme is quite general, each operator which operates on a base type
-can be iterated over the elements of an array. It seem to work well but
-defining each new operators requires writing a different C function.
-Furthermore in each function there are two hardcoded OIDs which reference
-a base type and a procedure. Not very portable. Can anyone suggest a
-better and more portable way to do it ?
-
-See also array_iterator.sql for an example on how to use this module.

contrib/bit/README

-A set of C routines to implement an SQL-compliant bitstring type.
-
-The file varbit.c contains the c-functions to implement both BIT and
-BIT VARYING. Both types are implemented in essentially the same way,
-except that BIT is zero padded to a specified length. I've tried to
-make this code as independent as possible of the byte length, but it
-is quite possible that there may be problems on machines that don't
-have 8 bits/byte (are there still any around?).
-
-The SQL standard only defines comparison, SUBSTR and concatenation
-operators, and these have been implemented. In addition all logical
-operators have been implemented, i.e. ~,|,&,^,<< and >>. This is
-useful if one wants to build bit masks. If the two strings are not of
-the same length the longer string is truncated (truncation was the
-only real option, as padding with zeros could give unintuitive results
-for ^) and the result has the length of the shorter string. If there
-is a requirement for any other functions, let me know, and I will have
-a look.
-
-My knowledge of postgres is not up to integrating a type, so I'm hoping
-that somebody can integrate this type for me, or give me some hints as
-to what needs to be done. These routines were developed outside the
-postgres source tree, with a hacked version of postgres.h. The header
-files probably need some ammending.
-
-The included files are 
-
-varbit.h       -- bit string header type
-varbit.c       -- the routines
-vartest.c      -- a few calls to the routines to 
-
-The following routines are available. 
-
-char * zpbitin(char *s, int dummy,  int32 atttypmod);
-	Read in a zero padded bit string of the form X'...' or B'...'
-    
-char * zpbitout(char *s);
-	Print a zero padded bit string in hex X'...'
-
-char * zpbitsout(char *s);
-	Print a zero padded bit string in binary B'...'
-
-char * varbitin(char *s, int dummy,  int32 atttypmod);
-	Read in a varying length bit string of the form X'...' or B'...'
-
-[There is no need for separate output functions for varying bit, as 
- zpbitout will print them out correctly]
-
-char * bitcat (char *arg1, char *arg2);
-	Bit concatenation. 
-
-char * bitsubstr (char *arg, int32 s, int32 l);
-	Substring of a bit string.
-
-bool biteq (char *arg1, char *arg2);
-bool bitne (char *arg1, char *arg2);
-bool bitge (char *arg1, char *arg2);
-bool bitgt (char *arg1, char *arg2);
-bool bitle (char *arg1, char *arg2);
-bool bitlt (char *arg1, char *arg2);
-int bitcmp (char *arg1, char *arg2);

-I have written some new funtions for time and date data types which can
-be used to extract hour,minutes,seconds from time values, and year,
-month,day from a date. There is also a time_difference and functions
-to convert a time to minutes or seconds.
-
-There are also new input/output functions for the time data type which
-allow the insertion of time attributes with value 24:00:00.
-This can be useful if your application needs to compute time difference
-from two time values representing an elapsed time of 24 hours.
