> Missing sql function, "replace".

>                 Key: SPARK-31628
>                 URL: https://issues.apache.org/jira/browse/SPARK-31628
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.4.4
>         Environment: Tested on v 2.4.4, spark-shell and in Scala Spark application.
>            Reporter: Dan Monroe
>            Priority: Minor

> In the spark sql functions docs, there is a function called [replace|[https://spark.apache.org/docs/latest/api/sql/index.html#replace]];
a non-regex string replace function that should have existed since 2.3.0.
> In the spark-shell and in Scala Spark apps (2.4.4) I cannot find this function inside
of the `org.apache.spark.sql.functions` package, and it does not appear to be defined in this
file for these versions:
> [https://github.com/apache/spark/blob/v2.3.0/sql/core/src/main/scala/org/apache/spark/sql/functions.scala]
> [https://github.com/apache/spark/blob/v2.4.4/sql/core/src/main/scala/org/apache/spark/sql/functions.scala]
>  
> However, I can find it in the function registry:
> [https://github.com/apache/spark/blob/v2.3.0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/FunctionRegistry.scala#L338]
> [https://github.com/apache/spark/blob/v2.4.4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/FunctionRegistry.scala#L337]
>  
> It's not a huge deal because there is still "regexp_replace", it's just a little misleading.
