Add new system view, pg_config Move and refactor the underlying code for the pg_config client application to src/common in support of sharing it with a new system information SRF called pg_config() which makes the same information available via SQL. Additionally wrap the SRF with a new system view, as called pg_config. Patch by me with extensive input and review by Michael Paquier and additional review by Alvaro Herrera. 2016-02-17 12:12:06 -05:00			`/*`

Cosmetic improvements in new config_info code. Coverity griped about use of unchecked strcpy() into a local variable. There's unlikely to be any actual bug there, since no caller would be passing a path longer than MAXPGPATH, but nonetheless use of strlcpy() seems preferable. While at it, get rid of unmaintainable separation between list of field names and list of field values in favor of initializing them in parallel. And we might as well declare get_configdata()'s path argument as const char *, even though no current caller needs that. 2016-02-21 11:38:24 -05:00			`extern ConfigData get_configdata(const char my_exec_path,`
