This specifies error severity level <literal>ERROR</> (a run-of-the-mill
error). The <function>errcode</> call specifies the SQLSTATE error code
- using a macro defined in <filename>src/include/utils/elog.h</>. The
+ using a macro defined in <filename>src/include/utils/errcodes.h</>. The
<function>errmsg</> call provides the primary message text. Notice the
extra set of parentheses surrounding the auxiliary function calls ---
these are annoying but syntactically necessary.
<function>errcode</>(sqlerrcode) specifies the SQLSTATE error identifier
code for the condition. If this routine is not called, the error
identifier defaults to
- <literal>ERRCODE_INTERNAL_ERROR</> when the error level is
+ <literal>ERRCODE_INTERNAL_ERROR</> when the error severity level is
<literal>ERROR</> or higher, <literal>ERRCODE_WARNING</> when the
error level is <literal>WARNING</>, otherwise (for <literal>NOTICE</>
and below) <literal>ERRCODE_SUCCESSFUL_COMPLETION</>.
</para>
<para>
- You may also see uses of the older function <function>elog</>. This
- is equivalent to an <function>ereport</> call specifying only severity
- level and primary message. <function>elog</> should only be used if
- the default errcode assignment is appropriate; this generally restricts
- its use to internal errors and debug logging output.
+ There is an older function <function>elog</> that is still heavily used.
+ An <function>elog</> call
+<programlisting>
+ elog(level, "format string", ...);
+</programlisting>
+ is exactly equivalent to
+<programlisting>
+ ereport(level, (errmsg_internal("format string", ...)));
+</programlisting>
+ Notice that the SQLSTATE errcode is always defaulted, and the message
+ string is not included in the internationalization message dictionary.
+ Therefore, <function>elog</> should be used only for internal errors and
+ low-level debug logging. Any message that is likely to be of interest to
+ ordinary users should go through <function>ereport</>. Nonetheless,
+ there are enough internal <quote>can't happen</> error checks in the
+ system that <function>elog</> is still widely used; it is preferred for
+ those messages for its notational simplicity.
