Hello.
We are trying to use geometry data with Apache Spark Connect and Apache
Sedona. We are able to convert binary geometry data to Sedona geometry types
using `ST_GeomFromWKB` on a local Apache Sedona instance, but when attempting
to do this via a remote Spark Connect server, the `ST_GeomFromWKB` function is
unable to be found (see below error). Are Sedona operations compatible with a
Spark Connect server?
```
pyspark.errors.exceptions.connect.AnalysisException: [UNRESOLVED_ROUTINE]
Cannot resolve function `ST_GeomFromWKB` on search path [`system`.`builtin`,
`system`.`session`, `spark_catalog`.`default`].; line 1 pos 0
```
## Actual behavior
```Python
from pyspark.sql import SparkSession
import pyspark.sql.functions as f
from sedona.spark import *
spark =
SparkSession.builder.remote("sc://<spark_connect_address>:<port>").getOrCreate()
url = "jdbc:postgresql://<database_address>"
sedona = SedonaContext.create(spark)
df = sedona.read.format("jdbc").option("url", url).option("dbtable",
"nyc_neighborhoods").load().withColumn("geom", f.expr("ST_GeomFromWKB(geom)"))
df.show()
```
Running this code produces the above error at `df.show()`. When we use
Sedona Spark in conjunction with our Spark Connect server without geospatial
data (i.e., we don't use `.withColumn("geom",
f.expr("ST_GeomFromWKB(geom)"))`), there is no error; the data is loaded and
made available with the `geom` column in the original binary form.
Note: We are using the PostGIS demo database found
[here](https://postgis.net/workshops/postgis-intro/).
## Steps to reproduce the problem
1. Start the Spark Connect server:
```
./sbin/start-connect-server.sh --packages
org.apache.spark:spark-connect_2.12:3.5.0,org.apache.sedona:sedona-spark-shaded-3.5_2.12:1.7.0,org.datasyslab:geotools-wrapper:1.7.0-28.5,org.postgresql:postgresql:42.7.4
--repositories https://artifacts.unidata.ucar.edu/repository/unidata-all
--executor-memory 28G
```
<br>
2. Run the Python code above.
## Settings
Sedona version = 1.7.0
Apache Spark version = 3.5.0
Scala version = 2.12
Python version = 3.8
