[Answered ]-No query executing on a table in postgresql

Most likely you are not terminating your query with a semicolon 😉

Note that by default the PostgreSQL prompt has three pieces:

[dbname][linestatus][is_superuser]

for example logged in as Postgres, new line, db is postgres:

postgres=#

Logged in to db test as non-superuser, new line:

test=>

Now that = is an important character. If you have an open paren, it will show:
test(>

If you are at the top level it will be

test->
