Re: pgAdmin4 Maintenance gives Database does not exist

I am not pgadmin4 support, but this looks to me like the problem is your naming convention.Per PostgreSQL (and SQL) object names MUST start with a letter.
https://www.postgresql.org/docs/9.6/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
So names a database with a number (even if quoted), is a no no.
Try renaming the database to db815, and see if the problem still exists.

When I right-click on the database, choose maintence, and run analyze, I am getting a ‘database does not exist’ error. For example, when I try to analyze database 815, I am getting the error :psql: FATAL: database ""815"" does not exist Note the datebase name has two double quotes. Could this be a configuration issue? Executine analyze in an sql window works fine.   Thanks, Mark Watson
