The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/11/ecpg-sql-connect.html Description:
Please add the note about the limitation characters in connection string. For example, I think that below explanation should be in the Parameter section of connection_target. ---- Note that this parameter does not allow the symbols with special meaning of the URI parts, e.g. "&" and "?". ----- I checked some symbols with special meaning of the URI parts whether it is able to use in connection_target, and I could not connect to database with the string containing "&" and "?". I reported this limitation in pg-general. https://www.postgresql.org/message-id/848B1649C8A6274AA527C4472CA11EDD5FC70CBE%40G01JPEXMBYT02
