Code completion does not work for tables with names containing spaces

System information:

• Operating system (distribution) and version Ubuntu 20.04, Amazon Linux 2
• DBeaver version 7.2.4
• Additional extensions Git

Connection specification:

• Database name and version Snowflake
• Driver name Snowflake JDBC, Postgresql JDBC 42
• Do you use tunnels or proxies (SSH, SOCKS, etc)? No

Describe the problem you’re observing:

Code completion (using control+space) rarely works. Most of the time it shows a window “no proposals”. This occurs both with and without an alias. Occurs more frequently with quoted table names.

No errors appear in the error log. Not solved after refreshing the schema.

Steps to reproduce, if exist:

1. Connect to a Postgresql or Snowflake database.
2. Create a script.
3. Start writing a query: Select t. from "<any table>" t
4. Place the cursor after “t.”
5. Press Control+Space

Expected behavior: a pop-up with column name, or an error message with the reason to absence of proposals. Current behavior: “no proposals” in the popup and no error messages.

Include any warning/errors/backtraces from the logs

None
