I know boolean mode, but what are the others.

I'm using the latest version of DataGrip from JetBrains and MySql database (also latest), when I press Ctrl+Q for quick reference about a SQL operator (say BETWEEN), nothing is being shown. If I press the same combination on table name I get the help tooltip.
Is there a way to link external documentation to this command?
this is an example about BETWEEN operator
There is no way to do that. Database documentation will appear only for built-in functions in some databases.
I have set my DataGrip database project to use the latest PostgreSQL dialect and driver, yet nowhere does it understand the PostgreSQL data types natively. For example, it will autocomplete varchar but not text.
https://www.postgresql.org/docs/10/static/datatype.html
Is it just not capable of this?
EDIT: Another example is the "Generate DDL" for a table will create a statement with uuid(max) instead of simply uuid.

The solution was to disable "Introspect using JDBC metadata". Thanks #num8er for their help.
I have for years used MS Access and its query tool that is used for making queries. This tool is so good that I have never been forced to do very much SQL programming myself. The query tool has done all the work.
However, now I have started using Postgres and the Graphical Query Builder in pgAdmin. It seems that the Graphical Query Builder is rather primitive: It cannot be used if you need an aggregate function like SUM or COUNT.
Is this really correct?
Does anybody know a better graphical query builder for PostgreSQL?
Until now I have 'solved' the problem by linking MS Access to the Postgres database through ODBC and used MS Access' query tool to generate SQL commands which I then copy into pgAdmin's Graphical Query Builder - and edit the SQL commands until everything is correct.
SQL Maestro has a query designer, although it is PC only, AFAIK

EMS SQL Manager also has a query designer

Try SQLeo, its free and has a specific feature (autosavepoint) to prevent
ERROR: current transaction is aborted, commands ignored until end of transaction block.
Try a browser-based query builder for PostgreSQL called Skyvia. And you don’t have to worry about which operating system it works. It works where a browser exists. Simply make a connection to your PostgreSQL database and start building your queries. See a sample below.
Note that you can still switch between SQL code and query builder if you want to, just like in MS Access. Get the details here.
I can run a query on views in SQL Developer 3.1.07 and it returns the results I expect. My co-worker, who is in Mexico using the same user, can connect to the same database, sees the same views, runs the same query and gets no results, even from a simple "select * from VIEWNAME" query. The column headers display, but no data. If he selects a view from the connections window and selects the DATA tab no data displays. This user does not have access to any tables on this specific database.
I'm not certain he is running the same version of Developer, but it's not far off. I have checked as many settings in SQL Developer that I think could be the issue, but see no significant difference in his settings from mine.
Connecting to another database allows him to access data in both tables and views
Any thoughts on what we're missing?
I know I'm a few years late, but check if the underlying view doesn't filter on something that is based on localisation! I just had the issue and it turned out to be a statment like this that was causing issues:
SELECT *
FROM sometable
WHERE language = userenv('LANG')
Copy the JDBC folder from your oracle home and copy it over to your c-workers machine. we had the same issue and replacing the JDBC folder worked.
Faced the same which got resolved when I checked the 'skip NLS settings' box. My query was returning zero results earlier but when I ran the same query again, I could see the table rows.
Since your co-worker is in a different country, most probably the NLS settings (related to the language) are the culprit here.
I was facing the same issue, turned out that the update to the database from my sqldevelolper was not commited to the main database, that's why, I was getting results on my sqldeveloper for that query, but from aws it was returning empty results. When I chatted with DBA, he could find stale data. After I committed the data from my sqldeveloper, the db was actually updated.
Our team is working on a Postgresql database with lots of tables and views, without any referential constraints. The project is undocumented and there appears to be a great number of unused/temporary/duplicate tables/views dirtying the schema.
We need to discover what database objects have real value and are actually used and accessed.
My inital thoughts were to query the Catalog/'data-dictionary'.
Is it possible to query the Postgresql Catalog to find an object's last query time.
Any thoughts, alternative approaches and or tools ideas?
Check the Statistics Collector
Not sure about the last query time but you can adjust your postgresql.conf to log all SQL:
log_min_duration_statement = 0
That will at least give you an idea of current activity.
Reset the statistics, pg_stat_reset(), and then check the pg catalog tables like pg_stat_user_tables and such to see where activity looks like its showing up.
