org.postgresql.util.PSQLException: Unknown type CHAR(10)[]

[bioball]

I have column whose type is CHAR(10)[], and am attempting to use an AdavancedArrayJdbcType to create a mapping into a scala class.

Here's how I'm creating the mapping in my source code:

  implicit val blocklyChallengeIdArrayType = new driver.AdvancedArrayJdbcType[BlocklyChallengeId](
    "CHAR(10)",
    stringToBlocklyChallengeId,
    blocklyChallengeIdToString
  ).to(_.toSeq)

  def stringToBlocklyChallengeId(s: String) = utils.SimpleArrayUtils.fromString(BlocklyChallengeId.apply)(s).getOrElse(Nil)
  def blocklyChallengeIdToString(v: Seq[BlocklyChallengeId]) = utils.SimpleArrayUtils.mkString[BlocklyChallengeId](_.toString)(v)

However, I'm getting this error:

Unable to update coordinates org.postgresql.util.PSQLException: Unknown type CHAR(10)[].

Looks to me like the postgres JDBC is trying to find the type that corresponds to "CHAR(10)[]", and not finding any. Is this a bug? Or what should my SQL base type be? Is there something I can reference for this?

[bioball]

Update: I tried switching my type to "VARCHAR(10)" and get the same issue. I also tried just "CHAR", but this chops off my whole string and only inserts the first char.

[tminglei]

@bioball yes, postgres JDBC can't find char(10)[]. The (10) impacted the finding.

Maybe you can try varchar[] or text[].

[bioball]

Changing it to "VARCHAR" worked. This seems broken to me, but I guess it doesn't matter if I represent this column as a varchar or text? The column in my table is still a CHAR(10).

[tminglei]

Yeah, seems char(10)[] column don't reject values char[]/varchar[]/text[].

[ploddi]

Got same issue with interger type. Seems like more AdvancedArrayJdbcType related than concrete sqlBaseType.

[tminglei]

@ploddi you mean integer[] not work?

[ploddi]

I got very strange issue. Investigating it now. I implement AdvancedArrayJdbcType for my custom type (enumuratum enumerations). On SOME integers I getting https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/jdbc/PgPreparedStatement.java#L1098 exception and other enums works just fine. Mb some slick or postgres driver related issue.
