\| \| \| \| \| \|	As it was agreed to worsen the code readability. Discussion: https://postgr.es/m/ecfcfb5f-3233-eaa9-0c83-07056fb49a83%402ndquadrant.com
*	Beautify initialization of JsonValueList and JsonLikeRegexContext	Alexander Korotkov	2019-03-17
\| \| \| \| \|	Instead of tricky assignment to {0} introduce special macros, which explicitly initialize every field.
*	Fix compiler warning in jsonpath_exec.c	Alexander Korotkov	2019-03-17
\| \| \| \| \| \| \|	Warning was observed in gcc 4.4.6, gcc 4.4.7 and probably others. Reported-by: Tom Lane Discussion: https://postgr.es/m/25151.1552751426%40sss.pgh.pa.us
*	Numeric error suppression in jsonpath	Alexander Korotkov	2019-03-16
\| \| \| \| \| \| \| \| \| \| \|	Add support of numeric error suppression to jsonpath as it's required by standard. This commit doesn't use PG_TRY()/PG_CATCH() in order to implement that. Instead, it provides internal versions of numeric functions used, which support error suppression.

*	Partial implementation of SQL/JSON path language	Alexander Korotkov	2019-03-16
	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.
