Hi i have installed postgres source using

pip3 install 'acryl-datahub[postgres]'

still its showing disabled

try

which python
which pip3
which datahub

to find out whether they are pointing to what you would expect

➜ which python3

/Library/Frameworks/Python.framework/Versions/3.6/bin/python3

➜which pip3

/Library/Frameworks/Python.framework/Versions/3.6/bin/pip3

➜which datahub

/Library/Frameworks/Python.framework/Versions/3.6/bin/datahub

can you give the complete output of

pip3 install 'acryl-datahub[postgres]'

Issue got resolved. Issue was with psycopg2 library
