show PostgreSQL server log (RM #6037)

[dpage]

Issue migrated from Redmine: https://redmine.postgresql.org/issues/6037 Originally created by Frank Limpert at 2020-11-24 15:09:50 UTC.

In pgAdmin3 (see attached screen shot), I can have a look inside the most recent PostgreSQL server log file. This helps me especially to tune SQL commands inside of functions using auto_explain et al. This feature would be especially helpful for developers not having shell access to their PostgreSQL server.

Older PostgreSQL servers might need EXTENSION adminpack for this. Newer PostgreSQL versions have pg_read_file().

@akshay-joshi Thank you for identifying my enhancement request as a duplicate #6696 What is the timeframe for implementing this feature and why was it removed from pgadmin4 in the first place, my I ask? Thanks!

[akshay-joshi]

@ronwildt

We have completely rewritten pgAdmin 4 in React/ Python and other web technologies. pgAdmin III is c++ based standalone application. pgAdmin 4 is a web + desktop application. We will prioritize it.

[ronwildt]

@akshay-joshi The info is appreciated. When might the team be adding this to the backlog and what might be the ETA for delivery of the feature? (looking to know for planning purposes on our end, fyi.) Thanks! :)

[akshay-joshi]

@ronwildt

Will see the feasibility and if possible will try to add this to the next release 7.7 on 21st September.

[ronwildt]

@akshay-joshi That would be totally awesome! Didn't expect the team might be able to do so that quickly. Looking forward to it. Have a great weekend, thx. :)

[akshay-joshi]

@ronwildt

We have check the feasibility, this feature is not straightforward and seems to be very complex. So definitely it won't be there in the next release v7.7

[ronwildt]

@akshay-joshi We appreciate the update and I figured it would not be easy if not already in development. Any idea when the feature may be planned and implemented?

[akshay-joshi]

@ronwildt

We will check the feasibility/analysis first and then we can priorities.

[ronwildt]

@akshay-joshi Sounds good, looking forward to learning about ETA on inclusion in pgadmin4! Have a great Labor Day weekend! :)

2.Add tool tip/help text for join and csv format.

3.Refresh button should be one at top.

4.Values for Granted column shown undefined -

All Fixed

[pravesh-sharma]

1. Loading / no message is being displayed for disconnected servers

Fixed

[yogeshmahajan-1903]

Some more issues - 1.Format of logs shown in text area does not change on changing log format.

Fixed 2.Download button for logs can be moved on left top corner inline with Log format field.

3.Scroll bar appears while changing log format. Fixed

4.Get fixed rows for all 3 sections and add scroll. Let's discuss with team

5.Logs get re-rendered on selection change of any db object. It should be only on server selection change.xed If user directly selects another server's db then how will you identify?

[yogeshmahajan-1903]

1.Getting error below while selecting not connected server.

2.Despite of disabled json format logging, I can select json format.

3.Message displayed when there is no log file seems to incorrect - 'Enable logging for server'. Logging is always enabled, only case file is not present or empty.

[yogeshmahajan-1903]

All issues are fixed.
