Tom Lane	8255c7a5ee	Phase 2 pgindent run for v12. ... Switch to 2.1 version of pg_bsd_indent. This formats multiline function declarations "correctly", that is with additional lines of parameter declarations indented to match where the first line's left parenthesis is.

Tom Lane	e481d26285	Clean up minor warnings from buildfarm. ... Be more consistent about use of XXXGetDatum macros in new jsonpath code. This is mostly to avoid having code that looks randomly different from everyplace else that's doing the exact same thing. In pg_regress.c, avoid an unreferenced-function warning from compilers that don't understand pg_attribute_unused(). Putting the function inside the same #ifdef as its only caller is more straightforward coding anyway. In be-secure-openssl.c, avoid use of pg_attribute_unused() on a label. That's pretty creative, but there's no good reason to suppose that it's portable, and there's absolutely no need to use goto's here in the first place. (This wasn't actually causing any buildfarm complaints, but it's new code in v12 so it has no portability track record.)	7 years ago

Alexander Korotkov	72b6460336	Partial implementation of SQL/JSON path language ... SQL 2016 standards among other things contains set of SQL/JSON features for JSON processing inside of relational database. The core of SQL/JSON is JSON path language, allowing access parts of JSON documents and make computations over them. This commit implements partial support JSON path language as separate datatype called "jsonpath". The implementation is partial because it's lacking datetime support and suppression of numeric errors. Missing features will be added later by separate commits. Support of SQL/JSON features requires implementation of separate nodes, and it will be considered in subsequent patches. This commit includes following set of plain functions, allowing to execute jsonpath over jsonb values: * jsonb_path_exists(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_match(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_query(jsonb, jsonpath[, jsonb, bool]), * jsonb_path_query_array(jsonb, jsonpath[, jsonb, bool]). * jsonb_path_query_first(jsonb, jsonpath[, jsonb, bool]). This commit also implements "jsonb @? jsonpath" and "jsonb @@ jsonpath", which are wrappers over jsonpath_exists(jsonb, jsonpath) and jsonpath_predicate(jsonb, jsonpath) correspondingly. These operators will have an index support (implemented in subsequent patches). Catversion bumped, to add new functions and operators. Code was written by Nikita Glukhov and Teodor Sigaev, revised by me. Documentation was written by Oleg Bartunov and Liudmila Mantrova. The work was inspired by Oleg Bartunov.
