Use of Aggregation Functions in slick-pg

[adithya-badidey]

Is it possible to use aggregation functions supported in Postgres 9.x+

List of function are at: http://www.postgresql.org/docs/current/static/functions-aggregate.html#FUNCTIONS-AGGREGATE-TABLE

Im particularly interested in "string_agg"

Cheers!

Hi @adithya-bm I have completed most of the development, but encountering an issue SI-8556, and I'm waiting for the help.

BTW, it depends on some changes I made on slick, so it can't be released until related slick changes were merged and released. I have sent out a pull request and you can watch its progress on issue.

Hi @adithya-bm some updates for pg aggregate support: The changes of slick #796 didn't suit to the authors' expected, so I turned to implement a @cvogt suggested solution. But currently pending on slick #818.

Will keep you updated. Thanks!

Hi, I was wondering if you had the change to look into aggregation method since the release of Slick 3? Hopefully, https://issues.scala-lang.org/browse/SI-8556 is not an issue anymore... (?)

@j-martin I'm busy on other working now. I'll continue on it when I had time.

What's the status of this?

[tminglei]

It was already implemented in slick-pg.

@tminglei that's what I thought but why is this issue still open?

Although, it doesn't work for any use case that I needed it for.
