Does the metabase supoort original postgresql syntax?

I want to write some sql contains the syntax introduced in the postgresql 12 official doc, but it seems that the metabase doesn't some complex syntax such as contains '@>' . Should I modify my sql statement or the metabase doesn't support it in fact?

Hi @zhanghaooo
Can you post an example query? Metabase supports any single-statement queries, though dollar quoting conflicts with how variable replacement is handled.
