    <p>Hi Regina,</p>
    <p>Thanks for explaining the reasons behind this. Yes, in hindsight
      putting a note up about deprecation could have helped, although in
      my case the function was part of some code I found on the Net and
      adjusted a little, so I didn't really have a reason to lookup the
      'ST_Accum' function in the Help up to now, so would still have run
      into this.</p>
    <p>Anyway, it is fixed now, and the code runs fine after switching
      to 'array_agg'.<br>
    </p>
    <p>Marco<br>

          <p>Hi Regina,<o:p></o:p></p>
          <p>Yes, I found this via Google. After the update, it now
            indeed errors out on a 404. ST_Collect also no longer
            mentions it, so that seems fine now.<o:p></o:p></p>
          <p>I do slightly wonder by the way why ST_Accum wasn't simple
            re-implemented as a wrapper around 'array_agg'. While I
            appreciate breaking changes may be necessary and are to be
            expected for a major version update like 2.x to 3.x, in this
            particular case, where wrapping the function would have been
            an easy solution, could have avoided breaking existing code
            with minimal effort and maintenance overhead.<o:p></o:p></p>
          <p>Anyway, the required code changes are luckily minimal as
            well, just replace 'ST_Accum()' with 'array_agg()' as per
            the OSGeo tickets I saw, so that is not a big deal. I have
            now implemented this in my own code.<o:p></o:p></p>

                          <p>One more question:<o:p></o:p></p>
                          <p>After successfully installing the PostGIS
                            3.0.1 extension using CREATE EXTENSION in
                            pgAdmin4 on PostgreSQL 12.3 on Ubuntu 20.04
                            Focal, I now ran into an issue where it
                            appears the 'ST_Accum' function is missing
                            in my PostGIS install. My code calls this,
                            and it failed. I then had a look at the
                            function list in pgAdmin, and indeed
                            'ST_Accum' is not listed. I do see loads of
                            other PostGIS functions, just 'ST_Accum'
                            seems missing (although I cannot garantuee
                            there are a few more missing functions, but
                            the list seems pretty comprehensive from a
                            quick look, and the CREATE EXTENSION call
                            went without a hitch).<o:p></o:p></p>
                          <p>Can you confirm you see 'ST_Accum' in your
                            PostGIS 3.0.1 function list if you look in
                            pgAdmin? The PostGIS Help does not mention

                                  <p>Thanks for the tip, but what did
                                    you do to remove the old install?
                                    Did you rely on Apt or Synaptic to
                                    remove the old libgeos version, or
                                    did you manually clean up folders? I
                                    had two versions of libgeos as well
                                    (3.7 and 3.8) if I remember well
                                    (need to start up the VM again to
                                    check), and removed the older one
                                    through Synaptic just leaving the
                                    3.8 version, but that wasn't enough
                                    to solve my particular issues.<o:p></o:p></p>

                                                          I have been
                                                          trying
                                                          different
                                                          things to fix
                                                          this for past
                                                          two days <br>
                                                          including
                                                          re-install,
                                                          but to no
                                                          avail. I have
                                                          also attempted
                                                          to include <br>
                                                          the UbuntuGIS
                                                          repository as
                                                          a potential
                                                          alternative
                                                          resource of
                                                          PostGIS <br>
                                                          packages, but
                                                          discovered the
                                                          UbuntuGIS
                                                          repository is
                                                          lagging behind
                                                          and <br>
                                                          doesn't yet
                                                          have packages
                                                          for 20.04LTS.<br>
