## Proposed changes
Expose the error msg from BE as the real fail reason recorded for schema
change tasks. To avoid too much memory usage, we just pick one among all
to record.

When the catalog attributes have not changed, refreshing the catalog
only requires processing the cache, without rebuilding the entire
catalog.
pick (#39180)
In #37565, due to the change in the calling order of finalize, the final
generated Plan will be missing the PREDICATES that have been pushed down
in Jdbc. Although this behavior is correct, before perfectly handling
the push down of various PREDICATES, we need to keep all conjuncts to
ensure that we can still filter data normally when the data returned by
Jdbc is a superset.
cherry-pick from master #39020
Problem:
when use delete from using clause and assign partition information, it
would delete more data from other partition
Solved:
add partition information when transfer delete clause into insert into
select clause
introduced by #38950, explain plan with sql cache will throw an exception
```
errCode = 2, detailMessage = Cannot invoke "org.apache.doris.nereids.trees.plans.Plan.treeString()" because "this.optimizedPlan" is null

## Proposed changes
this is brought by https://github.com/apache/doris/pull/38008
if use cast(FLOOR(MINUTE(time) / 15) as decimal(9, 0)) in group by
clause when sync materialized view. if downgrade from 2.1.6 to 2.1.5 or
upgrade 2.1.6 to 3.0.0
this may cause fe can not run. So revert the function.

before `corr(nullable_x, nullable_y)` will core dump. not fixed.
no need to patch in master because the refactor
https://github.com/apache/doris/pull/37330 already changed the
implementation context

Pick #38895
Before this pr, this api needs backends' ip and port as param, which is
hard to use. This pr modify it. If there is no param, doris will print
all backends WAL info.
The acceptable usage are as follows
```
curl -u root: "127.0.0.1:8038/api/get_wal_size?host_ports=127.0.0.1:9058"
{"msg":"success","code":0,"data":["127.0.0.1:9058:0"],"count":0}%
curl -u root: "127.0.0.1:8038/api/get_wal_size?host_ports="
{"msg":"success","code":0,"data":["127.0.0.1:9058:0"],"count":0}%
curl -u root: "127.0.0.1:8038/api/get_wal_size"
{"msg":"success","code":0,"data":["127.0.0.1:9058:0"],"count":0}%

mysql [(none)]>select round(timediff(now(),'2024-08-15')/60/60,2);
ERROR 1105 (HY000): errCode = 2, detailMessage = argument 1 requires datetimev2 type, however 'now()' is of datetime type
```
The reason is that the function parameter types were modified in
expectedInputTypes, which led to no match being found. The code here is
from a long time ago. Because the precision of datetimev2 could not be
deduced in the past, a separate implementation was made here. This code
can be safely deleted.

bp: #38400
When the `Export` statement specifies the `delete_existing_files`
property, each `Outfile` statement generated by the `Export` will carry
this property. This causes each `Outfile` statement to delete existing
files, so only the result of the last Outfile statement will be
retained.
So, we add a rpc method which can delete existing files for `Export`
statement and the `Outfile` statements generated by the `Export` will
not carry `delete_existing_files` property any more.

Added the computeSignature function for millisecond/microsecond
calculation functions to generate parameters and return values with the
appropriate precision.
Modified the microSecondsAdd function, which was used for constant
folding, because constant folding uses the precision of the parameters
for calculation. However, for millisecond/microsecond calculations, it
is necessary to set the precision to the maximum to ensure correct
display.
