2.2.6 Function Calls

The syntax for a function call is the name of a function (possibly qualified with a schema name), followed by its argument list enclosed in parentheses:

function_name ([expression [, expression ... ]] )

For example, the following computes the square root of 2:

sqrt(2)

The list of built-in functions is in section 7 Functions and Operators. Other functions can be added by the user.

The arguments can optionally have names attached. See section 2.3 Calling Functions for details.
