Very long metrics values

[adrienyhuel]

Hello,

We're using Coroot Pg Agent to get metrics from PostGreSQL, which works great.
Metrics are exposed to FluentBit, which scrape them, and finally send them to OpenTelemetry.

Though there is a problem with some metrics in FluentBit.
Some pg_top_query_* metrics can be very long, thousands of chars, and FluentBit can't process them.

Is there a possibility to add some kind of string truncating to all the query strings, to limit the length of the metrics ?

Thank you :)
