#
# This list serves as the basis for generating source files containing error
# codes. It is kept in a common format to make sure all these source files have
# the same contents.
# The files generated from this one are:
#
#   src/include/utils/errcodes.h
#      macros defining errcode constants to be used in the rest of the source
#
#   src/pl/plpgsql/src/plerrcodes.h
#      a list of PL/pgSQL condition names and their SQLSTATE codes
#
#   doc/src/sgml/errcodes-list.sgml
#      a SGML table of error codes for inclusion in the documentation
#
# The format of this file is one error code per line, with the following
# whitespace-separated fields:
#
#      sqlstate    E/W/S    errcode_macro_name    spec_name
#
# where sqlstate is a five-character string following the SQLSTATE conventions,
# the second field indicates if the code means an error, a warning or success,
# errcode_macro_name is the C macro name starting with ERRCODE that will be put
# in errcodes.h, and spec_name is a lowercase, underscore-separated name that
# will be used as the PL/pgSQL condition name and will also be included in the
# SGML list. The last field is optional, if not present the PL/pgSQL condition
# and the SGML entry will not be generated.
#
# Empty lines and lines starting with a hash are comments.
#
# There are also special lines in the format of:
#
#      Section: section description
#
# that is, lines starting with the string "Section:". They are used to delimit
# error classes as defined in the SQL spec, and are necessary for SGML output.
#
#
#      SQLSTATE codes for errors.
#
# The SQL99 code set is rather impoverished, especially in the area of
# syntactical and semantic errors.  We have borrowed codes from IBM's DB2
# and invented our own codes to develop a useful code set.
#
# When adding a new code, make sure it is placed in the most appropriate
# class (the first two characters of the code value identify the class).
# The listing is organized by class to make this prominent.
#
# Each class should have a generic '000' subclass.  However,
# the generic '000' subclass code should be used for an error only
# when there is not a more-specific subclass code defined.
#
# The SQL spec requires that all the elements of a SQLSTATE code be
# either digits or upper-case ASCII characters.
#
# Classes that begin with 0-4 or A-H are defined by the
# standard. Within such a class, subclass values defined by the
# standard must begin with 0-4 or A-H. To define a new error code,
# ensure that it is either in an "implementation-defined class" (it
# begins with 5-9 or I-Z), or its subclass falls outside the range of
# error codes that could be present in future versions of the
# standard (i.e. the subclass value begins with 5-9 or I-Z).
#
# The convention is that new error codes defined by PostgreSQL in a
# class defined by the standard have a subclass value that begins
# with 'P'. In addition, error codes defined by PostgreSQL clients
# (such as ecpg) have a class value that begins with 'Y'.

# databases, schemas, prepared statements, cursors, tables, columns,
# functions (including operators), and all else (lumped as "objects").
# (The first four categories are mandated by the existence of separate
# SQLSTATE classes for them in the spec; in this file, however, we group
# the ERRCODE names with all the rest under class 42.)  Parameters are
# sort-of-named objects and get their own ERRCODE.
#
# The same breakdown is used for "duplicate" and "ambiguous" complaints,
# as well as complaints associated with incorrect declarations.
