Also be aware that postgreSQL array fields will prefix the type name with an underscore (e.g. "_int4" or "_text"), while composite a.k.a. row-type fields will return type "record".

Because complete documentation is always helpful, here are all the PostgreSQL general purpose types as they are listed in the 8.1 documentation, and each corresponding string returned by pg_field_type(). bigint => int8 bigserial => int8 bit => bit bit varying => varbit boolean => bool box => box bytea => bytea character varying => varchar character => bpchar cidr => cidr circle => circle date => date double precision => float8 inet => inet integer => int4 interval => interval line => line lseg => lseg macaddr => macaddr money => money numeric => numeric path => path point => point polygon => polygon real => float4 smallint => int2 serial => int4 text => text time => time time with time zone => timetz timestamp => timestamp timestamp with time zone => timestamptz And for the record... (note the 7.4 client lib) # postmaster --version postmaster (PostgreSQL) 8.0.4 # ldd libphp4.so ... libpq.so.3 => /usr/lib/libpq.so.3 (0xb7ac8000) ...

The types returned are: bool int2 (smallint) int4 int8 (bigint) numeric float4 (real / float) float8 (double) timestamp date time varchar bpchar (fixed leng string, 'blank padded char') inet (ip address) money There are some other more esoteric types, e.g. 'circle', but these are the most common.
