>  This chapter describes the embedded <ACRONYM
CLASS="ACRONYM"
>SQL</ACRONYM
> package
  for <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
>. It was written by
  Linus Tolke (<CODE
CLASS="EMAIL"
>&#60;<A
HREF="mailto:linus@epact.se"
>linus@epact.se</A
>&#62;</CODE
>) and Michael Meskes
  (<CODE
CLASS="EMAIL"
>&#60;<A
HREF="mailto:meskes@postgresql.org"
>meskes@postgresql.org</A
>&#62;</CODE
>). Originally it was written to work with
  <ACRONYM
CLASS="ACRONYM"
>C</ACRONYM
>. It also works with <ACRONYM
CLASS="ACRONYM"
>C++</ACRONYM
>, but
  it does not recognize all <ACRONYM
CLASS="ACRONYM"
>C++</ACRONYM
> constructs yet.

>  This documentation is quite incomplete.  But since this
  interface is standardized, additional information can be found in
  many resources about SQL.
