Opening processing algorithm from history with Postgres input causes error

[aroche]

What is the bug or the crash?

When trying to open an algorithm from the processing history dialog and that algorithm used a Postgres table with the option "selected features only", an error occurs :

SyntaxError: invalid syntax 
Traceback (most recent call last):
  File "C:\Users/AUGUST~1.ROC/DOWNLO~1/PROGRA~1/OSGEO4W/apps/qgis/./python/plugins\processing\gui\HistoryDialog.py", line 183, in executeAlgorithm
    exec(script)
  File "", line 5
    processing.execAlgorithmDialog("native:buffer", {'INPUT':QgsProcessingFeatureSourceDefinition('dbname='mydb' host=localhost port=5432 sslmode=disable authcfg=0h04410 key='id' srid=2154 type=Point checkPrimaryKeyUnicity='1' table="public"."wt_detail" (geom) sql=not refused and status in ('in operation', 'construction in progress')', selectedFeaturesOnly=True, featureLimit=-1, geometryCheck=QgsFeatureRequest.GeometryAbortOnInvalid),'DISTANCE':10,'SEGMENTS':5,'END_CAP_STYLE':0,'JOIN_STYLE':0,'MITER_LIMIT':2,'DISSOLVE':False,'OUTPUT':'TEMPORARY_OUTPUT'})

                                                                                                           ^
SyntaxError: invalid syntax

It seems that when the input is treated as QgsProcessingFeatureSourceDefinition, the data source name is not escaped properly in the log.

Steps to reproduce the issue

1. Open a PostgreSQL table
2. select some features
3. run a processing algorithm on that layer (e.g. buffer) with the "only selected features" checked
4. Open the history processing dialog
5. Open the last run algorithm

@aroche this is a bit outdated, can you check with the latest point release?

I've just tested with 3.20.3, with the same problem.
