andr-sokolov opened a new issue, #1746:
URL: https://github.com/apache/cloudberry/issues/1746
### Apache Cloudberry version
_No response_
### What happened
```c
void
TruncateAOSegmentFile(File fd, Relation rel, int32 segFileNum, int64 offset,
AOVacuumRelStats *vacrelstats)
{
char *relname = RelationGetRelationName(rel);
int64 filesize_before;
Assert(fd > 0);
Assert(offset >= 0);
RelationOpenSmgr(rel);
filesize_before = rel->rd_smgr->smgr_ao->smgr_FileSize(fd);
if (filesize_before < offset)
ereport(ERROR,
(errmsg("\"%s\": file size smaller than logical
eof: %m",
relname)));
```
When the error happens, `filesize_before` is file size of the main fork of
`pg_aocsseg`, and `offset` is size of the first column file.
### What you think should happen instead
