# To use pgindent, set the PATH environment variable to include the directories
# containing the binaries pgindent and pg_bsd_indent. It is important to
# utilize a specific version of pg_bsd_indent, which sources can be found
# in the <postgresql>/src/tools/pg_bsd_indent directory, where <postgresql>
# is the root directory of the PostgreSQL project source tree.
#
# The sources of the utilities can be found in the following directories:
# - <postgresql>/src/tools/pgindent
# - <postgresql>/src/tools/pg_bsd_indent
#
# pgindent-typedefs.list should be updated every time after implementing
# new types and introducing new typedefs in the code. For details how
# to update pgindent-typedefs.list and for other information about pgindent,
# please, read the doc: <postgresql>/src/tools/pgindent/README.
#
# pgindent-excludes.list is used to specify files to be ignored.
