Peter Eisentraut a6554df4f7 In an effort to reduce the total number of chapters, combine the small 
chapters on extending types, operators, and aggregates into the extending
functions chapter.  Move the information on how to call table functions
into the queries chapter.  Remove some outdated information that is
already present in a better form in other parts of the documentation.

Bruce Momjian be2b660ecd This patch includes a lot of minor cleanups to the SGML documentation, 
including:

- replacing all the appropriate usages of <citetitle>PostgreSQL
...</citetitle> with &cite-user;, &cite-admin;, and so on

- fix an omission in the EXECUTE documentation

- add some more text to the EXPLAIN documentation

- improve the PL/PgSQL RETURN NEXT documentation (more work to do here)

- minor markup fixes

Tom Lane c82c9559a7 Minor updates/corrections for CREATE/DROP FUNCTION/AGGREGATE/OPERATOR. 2000-10-23 00:46:07 +00:00
Tom Lane bec98a31c5 Revise aggregate functions per earlier discussions in pghackers. 
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner.  Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.

Also, enable new LIKE selectivity estimators by default.  Unrelated
change, but as long as I had to force initdb anyway...
