highlight psql error

debug psql statements

when you get stuff like this:

5 UTC [1] LOG:  database system is ready to accept connections
db_1                | 2021-11-24 09:58:49.133 UTC [83] ERROR:  invalid input value for enum task_status: "ready" at character 339
db_1                | 2021-11-24 09:58:49.133 UTC [83] STATEMENT:  BEGIN;

its nice to be able to quickly figure out where the error is in the input sql file.
