OK, good start of discussion is define groups of the PostgreSQL functions:
1/ Extern compatible functions
The functions compatible with standards or customs or others SQL servers. For example trim, to_char, ... 2/
PostgreSQLspecific functions used in standard SQL operations (the function works with standard data and not load it
from internal PostgreSQL stuff).
For example convert(), all datetype function like int(). The name convenition must be like names in group 1/
3/ PostgreSQL specific system functions
For example pg_backend_pid(). IMHO clean solution is use "pg_" prefix.
4/ The calls without '( )'
For example "SELECT current_user;" IMHO right is not use "pg_" prefix _if_ you call it without braces. _But_ if
youcall it with '()' and function can be member of group 3/ is right use "pg_" prefix.
For example: SELECT current_user; SELECT pg_current_user();
5/ Deprecated functions
In docs marked as "deprecated" and will removed in some major release (for example in 8.0).
6/ ???
