Avoid scanning entire Geodatabase file

[marklit]

It appears an entire scan of a Geodatabase file is needed before a single record can be returned. The following pulls one record from an 870 MB file and takes ~36 seconds to do so.

select FIPS_CODE FROM st_read('SF_Professional_AK.gdb/a00000011.gdbtable') LIMIT 1;

┌───────────┐
│ FIPS_CODE │
│  varchar  │
├───────────┤
│ 11111     │
└───────────┘
