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.

Get rid of backtracking in jsonpath_scan.l Non-backtracking flex parsers work faster than backtracking ones. So, this commit gets rid of backtracking in jsonpath_scan.l. That required explicit handling of some cases as well as manual backtracking for some cases. More regression tests for numerics are added.

Remove ambiguity for jsonb_path_match() and jsonb_path_exists() There are 2-arguments and 4-arguments versions of jsonb_path_match() and jsonb_path_exists(). But 4-arguments versions have optional 3rd and 4th arguments, that leads to ambiguity. In the same time 2-arguments versions are needed only for @@ and @? operators. So, rename 2-arguments versions to remove the ambiguity. Catversion is bumped.

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.

Throw error in jsonb_path_match() when result is not single boolean jsonb_path_match() checks if jsonb document matches jsonpath query. Therefore, jsonpath query should return single boolean. Currently, if result of jsonpath is not a single boolean, NULL is returned independently whether silent mode is on or off. But that appears to be wrong when silent mode is off. This commit makes jsonb_path_match() throw an error in this case. Author: Nikita Glukhov
