`pgx` is a crate to wirte custom functions to postgres database.
It has `no_std` features to turn off std,(but I think in v2.0.0 we don't have
to turn off std for most crates.)
I used the `project template` in the samplecode folder.
Here is my `Cargo.toml` file:
```cargo.toml
[package]
name = "sample"
version = "1.0.0"
authors = ["XXX"]
edition = "2021"
[lib]
name = "sample"
crate-type = ["staticlib"]
[features]
default = ["pg15"]
pg11 = ["pgx/pg11"]
pg12 = ["pgx/pg12"]
pg13 = ["pgx/pg13"]
pg14 = ["pgx/pg14"]
pg15 = ["pgx/pg15"]
[dependencies]
pgx = {version = "0.6.1",default-features = false}
[dev-dependencies]
# uncomment these if compiling outside of 'pgx'
[profile.dev]
panic = "unwind"
lto = "thin"
[profile.release]
panic = "unwind"
opt-level = 3
lto = "fat"
codegen-units = 1
```

here is the compile output:

error: could not compile `proc-macro2` due to 3 previous errors

```
I think the real "problematic crate" may be `proc-marco2` crate.
