Update: The definition of the query to access the list of functions should be modified in phpPgAdmin to replace pg_proc.proisagg with pg_proc.prokind. See: https://dba.stackexchange.com/questions/238903/postgresql-11-error-column-p-proisagg-does-not-exist#238906

Update: Seems that this is a PostgreSQL problem, rather than a phpPgAdmin one. I get the same error using psql. The current ticket could now be closed.

column p.proisagg does not exist

Right, I had forgotten the .key file. Thanks!

@Paul: I got the same problem, importing a 1.24 format file into the 2.38 version. Although I followed all the steps you proposed, it gives me the same error message: "Failed to load the specified file!"
