<para>
The <application>PL/pgSQL</> call handler parses the function's source text and
produces an internal binary instruction tree the first time the
- function is called. The instruction tree fully translates the
+ function is called (within any one backend process). The instruction tree
+ fully translates the
<application>PL/pgSQL</> statement structure, but individual
<acronym>SQL</acronym> expressions and <acronym>SQL</acronym> queries
used in the function are not translated immediately.
