I don't know of any feature like that, but maybe you can do the following in your script/files: \set lastquery 'your-query-here' so that you can do something like explain :lastquery; But if you are able to manipulate your scripts you can just insert the explain by hand on queries you are interested in, or use autoexplain for all the queries.

It was my dream to have something we already have in shell - explain analyze !$ I think it should be not very difficult.

Re: [GENERAL] Analyzing last run query in psql
I'd like the execution plan to be in the psql output, not in the postgres log.
