|
|
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.

|
|
Each subdirectory contains a README file with information about the
|
2002-02-22 01:10:11 +01:00
|
|
|
module. Most items can be built with `gmake all' and installed with
|
|
|
|
|
`gmake install' in the usual fashion, after you have run the `configure'
|
|
|
|
|
script in the top-level directory. Some directories supply new
|
2004-06-01 07:15:47 +02:00
|
|
|
user-defined functions, operators, or types. In these cases, after you have
|
|
|
|
|
installed the files you need to register the new entities in the database
|
|
|
|
|
system by running the commands in the supplied .sql file. For example,

As mentioned above, here is my contrib/tablefunc patch. It includes
three functions which exercise the tablefunc API.
show_all_settings()
- returns the same information as SHOW ALL, but as a query result
normal_rand(int numvals, float8 mean, float8 stddev, int seed)
- returns a set of normally distributed float8 values
- This routine implements Algorithm P (Polar method for normal
deviates) from Knuth's _The_Art_of_Computer_Programming_, Volume 2,
3rd ed., pages 122-126. Knuth cites his source as "The polar
method", G. E. P. Box, M. E. Muller, and G. Marsaglia,
_Annals_Math,_Stat._ 29 (1958), 610-611.
crosstabN(text sql)
- returns a set of row_name plus N category value columns
- crosstab2(), crosstab3(), and crosstab4() are defined for you,
but you can create additional crosstab functions per directions
in the README.
