PostgreSQL Error Codes
error codes
list of
All messages emitted by the PostgreSQL
server are assigned five-character error codes that follow the SQL
standard's conventions for SQLSTATE> codes. Applications
that need to know which error condition has occurred should usually
test the error code, rather than looking at the textual error
message. The error codes are less likely to change across
PostgreSQL> releases, and also are not subject to
change due to localization of error messages. Note that some, but
not all, of the error codes produced by PostgreSQL>
are defined by the SQL standard; some additional error codes for
conditions not defined by the standard have been invented or
borrowed from other databases.
According to the standard, the first two characters of an error code
denote a class of errors, while the last three characters indicate
a specific condition within that class. Thus, an application that
does not recognize the specific error code can still be able to infer
what to do from the error class.
lists all the error codes defined in
PostgreSQL &version;. (Some are not actually
used at present, but are defined by the SQL standard.)
The error classes are also shown. For each error class there is a
standard> error code having the last three characters
000>. This code is used only for error conditions that fall
within the class but do not have any more-specific code assigned.
The PL/pgSQL> condition name for each error code is the
same as the phrase shown in the table, with underscores substituted
for spaces. For example, code 22012>, DIVISION BY ZERO,
has condition name DIVISION_BY_ZERO>. Condition names can
be written in either upper or lower case. (Note that
PL/pgSQL> does not recognize warning, as opposed to error,
condition names; those are classes 00, 01, and 02.)
