Not all functions are supported by all builds. It depends on your
|
|
libpq (The PostgreSQL C client library) version and how libpq is
|
|
compiled. If PHP PostgreSQL extensions are missing, then it is because
|
|
your libpq version does not support them.

Most PostgreSQL functions accept <parameter>connection</parameter> as
|
|
the optional first parameter. If it is not provided, the last opened
|
|
connection is used. If it doesn't exist, functions return &false;.

PostgreSQL automatically folds all identifiers (e.g. table/column names)
|
|
to lower-case values at object creation time and at query time.
|
|
To force the use of mixed or upper case identifiers, you must escape
|
|
the identifier using double quotes ("").

PostgreSQL does not have special commands for fetching database schema
|
|
information (eg. all the tables in the current database). Instead, there
|
|
is a standard schema named <literal>information_schema</literal> in
|
|
PostgreSQL 7.4 and above containing
|
|
system views with all the necessary information, in an easily
|
|
queryable form. See the <link xlink:href="&url.pgsql.manual;">PostgreSQL Documentation</link>
|
|
for full details.
