The following conventions are used in the synopsis of a command:
brackets ([
and ]
) indicate optional parts. (In the synopsis of a
Tcl command, question marks (?
) are
used instead, as is usual in Tcl.) Braces ({
and }
) and vertical
lines (|
) indicate that you must
choose one alternative. Dots (...
)
mean that the preceding element can be repeated.
Where it enhances the clarity, SQL commands are preceded by the
prompt =>
, and shell commands are
preceded by the prompt $
. Normally,
prompts are not shown, though.
An administrator is generally a person who is in charge of installing and running the server. A user could be anyone who is using, or wants to use, any part of the PostgreSQL system. These terms should not be interpreted too narrowly; this book does not have fixed presumptions about system administration procedures.
