100 * New-style error reporting API: to be used in this way:
101 * ereport(ERROR,
102 * errcode(ERRCODE_UNDEFINED_CURSOR),
103 * errmsg("portal \"%s\" not found", stmt->portalname),
104 * ... other errxxx() fields as needed ...);
105 *
106 * The error level is required, and so is a primary error message (errmsg
107 * or errmsg_internal). All else is optional. errcode() defaults to
108 * ERRCODE_INTERNAL_ERROR if elevel is ERROR or more, ERRCODE_WARNING
109 * if elevel is WARNING, or ERRCODE_SUCCESSFUL_COMPLETION if elevel is
110 * NOTICE or below.
111 *
112 * Before Postgres v12, extra parentheses were required around the
113 * list of auxiliary function calls; that's now optional.
114 *
115 * ereport_domain() allows a message domain to be specified, for modules that
116 * wish to use a different message catalog from the backend's. To avoid having
117 * one copy of the default text domain per .o file, we define it as NULL here
118 * and have errstart insert the default text domain. Modules can either use
119 * ereport_domain() directly, or preferably they can override the TEXTDOMAIN
120 * macro.
121 *
122 * When __builtin_constant_p is available and elevel >= ERROR we make a call
123 * to errstart_cold() instead of errstart(). This version of the function is
124 * marked with pg_attribute_cold which will coax supporting compilers into
125 * generating code which is more optimized towards non-ERROR cases. Because
126 * we use __builtin_constant_p() in the condition, when elevel is not a
127 * compile-time constant, or if it is, but it's < ERROR, the compiler has no
128 * need to generate any code for this branch. It can simply call errstart()
129 * unconditionally.
130 *
131 * If elevel >= ERROR, the call will not return; we try to inform the compiler
132 * of that via pg_unreachable(). However, no useful optimization effect is
133 * obtained unless the compiler sees elevel as a compile-time constant, else
134 * we're just adding code bloat. So, if __builtin_constant_p is available,
135 * use that to cause the second if() to vanish completely for non-constant
136 * cases. We avoid using a local variable because it's not necessary and
137 * prevents gcc from making the unreachability deduction at optlevel -O0.

319 * API for catching ereport(ERROR) exits. Use these macros like so:
320 *
321 * PG_TRY();
322 * {
323 * ... code that might throw ereport(ERROR) ...
324 * }
325 * PG_CATCH();
326 * {
327 * ... error recovery code ...
328 * }
329 * PG_END_TRY();
330 *
331 * (The braces are not actually necessary, but are recommended so that
332 * pgindent will indent the construct nicely.) The error recovery code
333 * can either do PG_RE_THROW to propagate the error outwards, or do a
334 * (sub)transaction abort. Failure to do so may leave the system in an
335 * inconsistent state for further processing.
336 *
337 * For the common case that the error recovery code and the cleanup in the
338 * normal code path are identical, the following can be used instead:
339 *
340 * PG_TRY();
341 * {
342 * ... code that might throw ereport(ERROR) ...
343 * }
344 * PG_FINALLY();
345 * {
346 * ... cleanup code ...
347 * }
348 * PG_END_TRY();
349 *
350 * The cleanup code will be run in either case, and any error will be rethrown
351 * afterwards.
352 *
353 * You cannot use both PG_CATCH() and PG_FINALLY() in the same
354 * PG_TRY()/PG_END_TRY() block.
355 *
356 * Note: while the system will correctly propagate any new ereport(ERROR)
357 * occurring in the recovery section, there is a small limit on the number
358 * of levels this will work for. It's best to keep the error recovery
359 * section simple enough that it can't generate any new errors, at least
360 * not before popping the error stack.
361 *
362 * Note: an ereport(FATAL) will not be caught by this construct; control will
363 * exit straight through proc_exit(). Therefore, do NOT put any cleanup
364 * of non-process-local resources into the error recovery section, at least
365 * not without taking thought for what will happen during ereport(FATAL).
366 * The PG_ENSURE_ERROR_CLEANUP macros provided by storage/ipc.h may be
367 * helpful in such cases.
368 *
369 * Note: if a local variable of the function containing PG_TRY is modified
370 * in the PG_TRY section and used in the PG_CATCH section, that variable
371 * must be declared "volatile" for POSIX compliance. This is not mere
372 * pedantry; we have seen bugs from compilers improperly optimizing code
373 * away when such a variable was not marked. Beware that gcc's -Wclobbered
374 * warnings are just about entirely useless for catching such oversights.
375 *
376 * Each of these macros accepts an optional argument which can be specified
377 * to apply a suffix to the variables declared within the macros. This suffix
378 * can be used to avoid the compiler emitting warnings about shadowed
379 * variables when compiling with -Wshadow in situations where nested PG_TRY()
380 * statements are required. The optional suffix may contain any character
381 * that's allowed in a variable name. The suffix, if specified, must be the
382 * same within each component macro of the given PG_TRY() statement.
