Since commit d26a810eb, we've defined bool as being either _Bool from <stdbool.h>, or "unsigned char"; but that commit overlooked the fact that probes.d has "#define bool char". For consistency, make it say "unsigned char" instead. This should be strictly a cosmetic change, but it seems best to be in sync. Formally, in the now-normal case where we're using <stdbool.h>, it'd be better to write "#define bool _Bool". However, then we'd need some build infrastructure to inject that configuration choice into probes.d, and it doesn't seem worth the trouble. We only use <stdbool.h> if sizeof(_Bool) is 1, so having DTrace think that bool parameters are "unsigned char" should be close enough. Back-patch to v12 where d26a810eb came in.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
