* add postgresql datasource * add rest of files for postgres datasource * fix timeseries query, remove unused code * consistent naming, refactoring * s/mysql/postgres/ * s/mysql/postgres/ * couple more tests * tests for more datatypes * fix macros for postgres * add __timeSec macro * add frontend for postgres datasource * adjust documentation * fix formatting * add proper plugin description * merge editor changes from mysql * port changes from mysql datasource * set proper defaultQuery for postgres * add time_sec to timeseries query accept int for value for timeseries query * revert allowing time_sec and handle int or float values as unix timestamp for "time" column * fix tslint error * handle decimal values in timeseries query * allow setting sslmode for postgres datasource * use type switch for handling data types * fix value for timeseries query * refactor timeseries queries to make them more flexible * remove debug statement from inner loop in type conversion * use plain for loop in getTypedRowData * fix timeseries queries * adjust postgres datasource to tsdb refactoring * adjust postgres datasource to frontend changes * update lib/pq to latest version * move type conversion to getTypedRowData * handle address types cidr, inet and macaddr * adjust response parser and docs for annotations * convert unknown types to string * add documentation for postgres datasource * add another example query with metric column * set more helpful default query * update help text in query editor * handle NULL in value column of timeseries query * add __timeGroup macro * add test for __timeGroup macro * document __timeGroup and set proper default query for annotations * fix typos in docs * add postgres to list of datasources * add postgres to builtInPlugins * mysql: refactoring as prep for merging postgres Refactors out the initialization of the xorm engine and the query logic for an sql data source. * mysql: rename refactoring + test update * postgres:refactor to use SqlEngine(same as mysql) Refactored to use a common base class with the MySql data source. Other changes from the original PR: - Changed time column to be time_sec to allow other time units in the future and to be the same as MySQL - Changed integration test to test the main Query method rather than the private transformToTable method - Changed the __timeSec macro name to __timeEpoch - Renamed PostgresExecutor to PostgresQueryEndpoint Fixes #9209 (the original PR) * postgres: encrypt password on config page With some other cosmetic changes to the config page: - placeholder texts - reset button for the password after it has been encrypted. - default value for the sslmode field. * postgres: change back col name to time from time_sec * postgres mysql: remove annotation title Title has been removed from annotations * postgres: fix images for docs page * postgres mysql: fix specs
