Description:

test=>> \sf+ app_con<TAB><TAB>

test=>> \sf+ app_config

ERROR: more than one function named "app_config"

I expect to see arguments types: void or jsonb like:

test=>> \sf app_con<TAB><TAB>

void jsonb

Because definition for those functions are:
Schema | Name | Result data type |

--------+------------+------------------+------------------------------------------------>
public | app_config | void | config jsonb

public | app_config | jsonb | keys text[] DEF

Best regards.

btw autocompletion for "DROP FUNCTION" works as expected
=> drop function app_config (
jsonb) text) text[])

I expect the similar behaviour for \sf+
