The following conventions are used in the synopsis of a command:
|
|
brackets (<literal>[</literal> and <literal>]</literal>) indicate
|
|
optional parts. (In the synopsis of a Tcl command, question marks
|
|
(<literal>?</>) are used instead, as is usual in Tcl.) Braces
|
|
(<literal>{</literal> and <literal>}</literal>) and vertical lines
|
|
(<literal>|</literal>) indicate that you must choose one
|
|
alternative. Dots (<literal>...</>) mean that the preceding element
|
|
can be repeated.

Where it enhances the clarity, SQL commands are preceded by the
|
|
prompt <literal>=></>, and shell commands are preceded by the
|
|
prompt <literal>$</>. Normally, prompts are not shown, though.

An <firstterm>administrator</firstterm> is generally a person who is
|
|
in charge of installing and running the server. A <firstterm>user</firstterm>
|
|
could be anyone who is using, or wants to use, any part of the
|
|
<productname>PostgreSQL</productname> system. These terms should not
|
|
be interpreted too narrowly; this book does not have fixed
|
|
presumptions about system administration procedures.
