Is there incompatibility and errors between Internet explorer and Postgresql?

Question

In my work we use Postgresql version 9.0 as a database for several systems. Some customers inform us that sometimes they cannot find certain search data using Internet Explorer 9, 10 and 11. I as a developer use Firefox and sometimes Chrome and can never find these errors. I believe there is some incompatibility of this database with the same IE. Is this true? There is even a compatibility problem like IE?

Answer 1

The problem certainly lies in the way the research is done. You’re not finding any differences in the results shown depending on the browser brand. Is finding differences depending on who is using the system.

It’s even possible to have different data being presented in different browsers, but it shows that your pages are more complex than they should be and are poorly tested. I’m not saying you have this problem, I’m just saying it’s possible, although highly unlikely. If you think this could be it, that there’s something on the page that might be hiding data in IE, open a specific question and show your code that you think you’re doing this. There is no way to analyze without seeing code. But reinforcement that is unlikely to have any problem.

But answering your question objectively incompatibility between the database and any browser not because they even talk to each other.

Anyway you can test this easily. Use IE and see if anything changes. And/or have your customers test with another browser (I know this is a little more complicated to do depending on the client) and the result will be the same. That is, I would discard any problem with the browser but do the test to be sure, there is no better way to find out.

Lastly you may still be curious about the problem. If there really is a problem and there is no error in the interpretation of the data by the clients or by you, probably the error is in the server-side application. Probably under certain circumstances it recovers the data one way or another.

Can the browser influence this? Yes, it can, but again it is highly unlikely. Your application would need to treat the data differently depending on the information from which browser the user is using being captured through Javascript and sent to the server. But all this is speculation and if it were, you’d know.

Answer 2

Database does not influence the browser the client is using, what may be influencing are the Javascript files being loaded on the page. Some function may be compatible with one browser but not with the other, as is the case with Internet Explorer as you are speaking.

The database is present on the server side, who is responsible for managing driver settings can be a server like Tomcat, Wilfly or Apache (if you use PHP)therefore there is no incompatibility between the browser belonging to the client side with Postgresql or another database belonging to the server side. Is that clear? Any doubt we’re here.
